The ECU is the Engine Control Unit this is the electronic box in the car that tells the engine, transmission, brakes, airbags, multiple sensors and many more moving pieces of the car what to do, when to do it, and for how long. Think of it as the brain, it tells the coils to fire the spark plugs that ignite the gas that moves the pistons that cranks the torque converter that turns the transmission that rotates the driveshaft that turns the axles that makes the wheels go round. Long story short, it makes the car go. If no ECU no go.
An ecu for this car would cost about $120
replace ECU with identical ECU
would the ECU cause misfiring
Assuming you mean the engine ECU, the answer is no
There is not a single ECU sensor. There are dozens of sensors on this car that feed the ECU
Depending on what part of the ecu is bad, yes.
A person can remove the ECU of the car and remove the resistor clips to help the car make the change. However, it is suggested to take the ECU to an automotive shop and have it flashed and changed over, to make sure it is done correctly.Ê
It varies from car to car, need more info.
No.
dohc?
No. ECU generally stands for Engine Control Unit, i.e. the brain or nerve centre for engine. Without it - no go. With that said, not all cars have an ECU. An older car with a carburetor, old-fashioned distributor and all that will run quite happily entirely without anything even remotely similar to an ECU. A Diesel car may not have an ECU etc etc.
An ECU is any of the electronic control units (computers) on the car.
