Passport EX 4WD V6-3165cc 3.2L DOHC MFI (2001)
7.
Modify the original APPS by cutting the connector housing off of the sensor.
8.
Connect the 10P connector to the modified APPS connector housing.
9.
Using a DVOM, check the voltage between the reference voltage pin for each sensor and ground.
^
If the sensor circuits all read 5.0 volts, go to step 11.
^
If any sensor circuit is above or below 5.0 volts, go to step 10.
10.
Troubleshoot for an internal short in another sensor or a PCM malfunction.
^
To find the sensor with an internal short, monitor the incorrect reference voltage, and disconnect each sensor (FTPS, EGR, MAP, TPS, CKP,
and CMP) one at a time until the reference voltage reads 5.0 volts. Replace that sensor, and repeat step 3.
^
To find a malfunctioning PCM, replace it with a known-good PCM. If all three sensors (APP Sensor 1, APP Sensor 2, and APP Sensor 3) are
within range, the original PCM is faulty; replace it and repeat step 3.
