5 to 45 This is a normal operating range.
Just because the the mansion copenhagen brothel module is corroded, does not mean it is bad.
This is the signal and monitor wire so the PCM can control the fuel pump driver module and know what the results are.
The pink wire with black stripe and a brown wire with white stripe goes directly to the fuel pump inside the fuel tank.Here is are some pictures of the fuel pump driver module located above the spare tire. I have put together a list of both below. When this 1998 escort zx2 throttle cable adjustment happens, the fuel pump relay energizes and sends power to the inertia switch and then allows power through (if the inertia switch is not tripped) to the fuel pump driver module. Ford uses a pulse width modulated.
Note: Certain vehicles the fpdm functions are incorporated in the Rear Electronics Module (REM).
Based on my experience, this code will also set if there is no or low fuel pressure.
One of the easiest ways to diagnose this no start issue is by using a scan tool that can read live data from data stream.
They are as follows.Fpdm will send a 50 duty cycle signal back to the PCM on the FPM circuit indicating everything is functioning properly.If the fpdm sees this request, it will send back the 25 duty cycle signal to the PCM.Also, the REM does not use an FPM circuit.No action will be taken by the fpdm 52 to 68 The PCM will not send this signal to the fpdm.The PCM sets the DTC when the message is received. Upon checking, the truck had spark but no fuel pressure when cranking. When starting the engine, the PCM sends a low current voltage down the FPM circuit.An open circuit cannot be detected in this range.The diagnostic trouble code P1233 code indicates an issue with the fuel pump driver module.
Damaged PCM, the power for the fuel pump circuit starts at the PCM power relay which is located inside the vehicle in the central junction box on the right a-pillar (right kick panel).
Possible Causes, escort/Tracer (only fpdm PWR circuit is open, or the ccrm pin 11 is open to battery voltage, or the ccrm is damaged.
