What Should You Know When Purchasing An Engine Control Module?

 

An engine part may need a replacement for several reasons. Replacing engine parts like an Engine Control Module with a new one is expensive; a used part could help you save on the cost. Selecting a used ECM is not a bad idea if you buy from the right place. Salvage yards or junkyards may store used car engines and their parts, but you cannot be too sure about the part's history. The part's condition too would be unknown to you if you are not an expert. Buying used engines or engine parts come with some undeniable risks, but you can reduce the risk if you know what to check when buying the used engine parts. 

What is an Engine Control Module?

• It is a component of any automotive mechatronic system.
• This unit controls both engine and transmission.
• Also called the Engine Control Unit ECU, it controls the injection of the fuel.
• The engine's crankshaft position sensor determines the position of the engine observing if the injectors and ignition system are activated at the exact time.
• The ECU keeps the mixture of air and gas tightly controlled in modern cars, replacing the earlier carburetor, more intelligently.
• The ECU controls the fuel injection, ignition and ancillaries of the engine.
• It uses digitally stored equations and numeric tables doing away with analogue means. 
  

What variables does the ECU deal with within the perfect ratio?

• The engine's demand.
• The coolant and engine temperature.
• The air temperature.
• The temperature of the fuel. 
• The quality of the fuel.
• Varying filter restriction.
• Meeting the air pressure.
• Observing the engine's pumping efficiency.

The working of the ECU

• The ECU is the brain of the engine., a computer that is responsible for power management on a limited scale. 
• It comprises temperature and pressure sensors, on/off signals, and data from other modules within the vehicle. 
• It collects the information and makes decisions. 
• Once the data is collected by the ECU from the software stored in its unit, it processes depending on output specifications like the fuel injector pulse width.
• The processor leads the software to decide on the appropriate output and records specifications like mixture adjustment and mileage.
• These help the ECU to perform the necessary action on the engine by dispensing the precise power to control the actuators.
• It includes the control of fuel injector pulse width, the exact timing of the ignition system, opening of an electronic throttle body or the activation of a radiator cooling fan.
• The ECU, to function properly, needs internal power and many internal components. 

ECU basic function

• ECU need sophisticated power management.
• It has a variety of components.
• The ECU regulates 1.8V, 2.6V, 3.3V, 5V, 30V and up to 250V of cars from the 10-15V supply.
• The ECU has full control over its power management till the ignition is on.
• When it receives the correct voltage, the microprocessor boots up and reads software from memory doing a self-check.
• Reading data from several sensors in the engine converts them into useful information.
• The CANbus, an internal computer car network that transmits information to other electronic modules. 
• Once the information has been interpreted by the microprocessor, it activates the output based on the numeric tables and formulae within the software.
  

The ECU is monitored individually by its microprocessor that determines the readings within the tolerance level. If the sensor readings fail and fall out of the tolerance level beyond the predetermined time, a fault is registered, and the fault code is retrieved by a technician.

What are fault codes?

Logic within the software is skipped or bypassed with a fluctuation in the engine efficiency when the engine is still working at a basic level. Sometimes the fault is determined at the self-diagnosis level and the engine automatically shuts down for safety.

Technicians access the fault codes after a diagnosis into the ECU memory. The fault code is a 5-digit alphanumeric code that starts with P, B, C or a U followed by 4 digits. The technician can ascertain the exact nature of the problem from the code.

When should you replace your ECU?

• Repairing an ECU can be tricky.
• It involves a complete disassembly and is an extremely precise and detailed electronic operation, just like repairing a computer or smartphone. 
• They are highly advanced pieces of technology that affects every component of the engine. 
• Replacement of a damaged ECU is a better alternative. 
• A trusted online used engine store will reprogram and ship and undamaged originally retrieved ECU from an undamaged vehicle. 
• The old data from the ECM will be cleared and newly programmed for you. 
• A trusted online store like Big Mouth Direct will match the ECU with your car model and year. You may also get an updated version. 
• You will save thousands of dollars when compared to an OEM Engine Control Unit. 
• Repairing the engine computer can get complicated and you can run into various problems ending up spending more than purchasing a used engine control unit.
  

What to check when buying a used ECU?

• Run a scan via the OBD2 port if you can.
• That could show a recently cleared fault code.
• Ask the dealer what codes were cleared and why. 
• Check the unit for an external chip. 
• Check the number on the label (by all the bar codes) and match yours, the last three digits are important.

Why trust Big Mouth Direct?

• Warranty offered for 30 days. 
• They have a thorough understanding of the part and each part is fully checked before delivery.

Is a used Power Steering Pump a good buy?

 

An electric power steering pump is an essential component of a vehicle that pushes the oil through the pipes up to the power steering system. This has a reservoir, that during steering, inserts the oil into a piston which acts as a lever on the steering. You should know when it needs to be replaced. Once you spot the signs you can order a used power steering pump and save your dollars with an intelligent buy.

A power steering pump helps drivers to steer the vehicle with improved steering efforts. All steering pumps are designed with a rotor and the style of the rotor defines the type of the steering pump. Steering pumps are of three types of Rotary Vane, Roller Steering, Slipper Power Steering.

The slotted rotor of the Power steering pumps is supported and located close to the cam wall and creates a semi-circular cavity.  Two separate side plates seal the rotor into the cam. The rotation makes the fluid enter the pump. The centrifugal force or hydraulic pressure/ pushrod pushes the vanes to the walls of the house. The fluid is pushed into the pumping chamber by the housing and the cam push fluid. The fluid penetrates the pockets made by the rotor, vanes, cam and side plates.

When does the power steering pump need replacement?

The power steering pump replacement should be made when you hear groaning noises that increase with negligence. The lack of fluid damages the system and replacement is the only way out. Watch the signs:

• Whining noises when the wheels turn.
• Slow response in the steering wheel
• Stiffness in wheels 
• Squealing sound when the vehicle starts.
  

What to check when buying a used electric power steering pump?

• Check the tension in the steering pump belt.
• Inspect thoroughly the pump hose for leaks and damages.
• Check if the steering is stiff.
• Mention the part number to get a perfect match. They may come in a stamped or sticker format on the housing. The location varies from model to model.

Why Is the Transmission So Important?

Why is the Transmission so Important? 

The transmission is an important automobile component. It transfers power from the engine to the driveshaft and the rear wheels or the axle half shaft and front wheels depending on the vehicle. Vehicles have an automatic or manual transmission. In stick shift vehicles, drivers need to control the stick to operate the vehicle. 

How does the transmission work? 

The transmission combines the gearsets with a torque or fluid coupling converter. The torque converter connects the engine to the transmission and uses pressurized fluid to transfer power to the gears. When the vehicle stops the transmission disconnects the engine from the drive wheels.  The transmission gradually runs the engine from stop position to motion with ease until the vehicle takes on a steady speed. 

Manual Transmissions

These have a clutch pedal and a shifter that the driver uses to change gears manually. The driver must know when and which gear to use by controlling the clutch. This transmission involves the flywheel, pressure plate and clutches to connect the engine with the transmission. 

The transmission is connected to the engine via a flywheel, pressure plate and a clutch. Each time a gear has shifted the clutch is pushed. 

Manual transmissions come in various types: 

Dual-Clutch

• Uses two separate clutches for even (2, 4, 6) and odd (1,3,5 and reverse) gears. 
• Common in older and race cars. Today’s cars have automated double transmissions with computer controls that adjust the gear shifting process and ease manual gear changing. 

Unsynchronized

These strong transmissions wereused by trucks in the 1960s. Unsynchronized transmissions also called rock crushers as the drivers grind the gears together getting them to mesh. 

Synchronized/Constant Mesh

The cluster gear, drive gear and mainshaft gears move constantly. The transmission uses pads to slow the gear down. You do not need a double-clutching action in this. 

Automated  

A transmission with computer-controlled shifting and a clutch is also called ATM.  It is a manual transmission used in heavy-duty trucks.

Single-Clutch

A single clutch manual transmission with the shift and clutch is controlled by a computer or electric hydraulic or electrohydraulic. Dual clutches took over these with a capacity to handle more torque. 

Automatic Transmissions

Processing the power, they do not use the clutch and rely on the torque convertor to switch gears. However, most SUVs and trucks use traditional automatic transmissions. The following components make an automatic transmission. 

Direct-shift gearbox: This gearbox has two clutches that disconnect alternatively, provides smooth acceleration and fast shifting. 

Tiptronic: This gearbox allows manual shifting of the automatic transmission, through the shifter or steering wheel controls. If the transmission is outside the parameters, then the computer will not allow the manual mode. 

Hydraulic: The fluid pressure present inside the automatic transmission.

Electric cars

These use Single-gear systems, have compact single-speed transmissions that transfer power to the drive wheel. It can be combined with the motor or bolt-on

CVT Transmissions

A pulley-based continuously variable transmission (CVT) is used in small vehicles with small engines and used in a snow machine. These are also popular in hybrid vehicles. It uses a primary small drive and a secondary large driven clutch connecting the two with a belt or chain.

 

When to replace the transmission?  

Automatic transmissions fail between 80,000 and 150,000 miles. 

Manual transmissions can fail sooner at 80,000 miles.

• Problems in shifting gears and your vehicle jerks or shakes
• Strange sounds coming from your engine when you shift gears.
• Excessive friction causes the transmission fluid to burn.
• Blot fluid on a paper towel to check leakage.
• Transmission fluid has a reddish or orange color, dark reddish or dark orange suggests dirt buildup.

Why should you buy a used transmission? 

• Used transmission on sale is 80% cheaper than original transmission.
• You can find a transmission that is identical to a new one.
