FUEL PUMP PWM CONTROL CIRCUIT
The Output Driver Module (ODM) is used by the PCM to turn on
many of the current-driven devices that are needed to control various
engine and transaxle functions. Each ODM is capable of controlling up
to 7 separate outputs by applying ground to the device which the PCM
is commanding on. ODM have the capability of diagnosing each output
You likely won't notice any drivability problems.
- Improper voltage level detected on fuel pump speed control
Pulse Width Modulated (PWM) circuit.
- Check for shorts or bad connections on fuel pump speed control
- Test fuel pump relay.
- Replace fuel pump control module.
