Turn the ignition off.
Connect the Powertrain Control Module (PCM) connector.
Connect a jumper wire between the (K152) TIP Return circuit and the (K153) TIP Signal circuit in the
Throttle Inlet Pressure Sensor harness connector.
Turn the ignition on.
With the scan tool, read the Throttle Inlet Pressure Sensor signal voltage.
NOTE: The voltage should be approximately 0.0 volts (plus or minus.1 volt) with the jumper wire in
place.
Does the scan tool display the voltage as described above?
Yes

THROTTLE INLET PRESSURE SENSOR
Using the wiring diagram/schematic as a guide, inspect the wiring and connectors between the Throttle
Inlet Pressure Sensor and the Powertrain Control Module (PCM).
Look for any chafed, pierced, pinched, or partially broken wires.
Look for broken, bent, pushed out or corroded terminals. Verify that there is good pin to terminal
contact in the related connectors.
Monitor the scan tool data relative to this circuit and wiggle test the wiring and connectors.
Look for the data to change or for the DTC to reset during the wiggle test.
Refer to any Technical Service Bulletins that may apply.
Were any problems found?
Yes
Repair as necessary.
Perform .
No
Replace and program the Powertrain Control Module (PCM) in accordance with the Service
Information.
