Where is the ECM on a Honda Accord?
The 2003 Honda Accord ecm location is behind the center of the dash up under it on the floor.
Why is my engine not responding to my ECM?
This can happen for any number of reasons, but usually, it’s a problem with your engine timing. While that function is directly controlled by the ECM, your PCM may also be at fault, since the ECM requires feedback from the PCM to adjust timing. 6.
What does it mean when your PCM is not working?
The presence of fault codes means something else is wrong that needs to be diagnosed and repaired. So until the real problem is found and fixed, the PCM may not function normally. If the engine control system is not going into closed loop, chances are the coolant sensor or oxygen sensor are not working properly.
Why does my car have a single PCM?
The reason is your car’s computer system. These systems are primarily controlled by a single computer: the powertrain control module (PCM). This controls the engine control module (ECM) and the transmission control module (TCM).
What to do if your ECM goes off?
Look for damaged, burnt, shorted, disconnected, or corroded wiring and/or connectors. Make repairs as required, clear all codes, and operate the vehicle for at last one complete drive cycle to see if the code returns.
What causes the ECM in a car to fail?
The most common source of ECM failure is in one of the wiring harnesses. If the wires to the transmission or fuel injectors become corroded, they can lose conductivity, leading to a failure. Fortunately, these issues can usually be resolved by replacing the corroded wires. If one of the wires shorts out to the frame, the ECM may fail entirely.

Is the ECM the same as the TCU?
The ECM is also sometimes referred to as the PCM (power-train control module), which consists of the engine control unit (ECU) and the transmission control unit (TCU). The ECM houses different codes, protocols and standard diagnoses for troubleshooting engine performance.
