P0932-LINE PRESSURE SENSOR CIRCUIT (CONTINUED) 2. CONDITION P0932 PRESENT CAUTION: Apply Parking Brake CAUTION: Firmly apply the brakes. While firmly applying the brakes, place the shifter in reverse, then slowly press the accelerator pedal to a TPS Compare the Line Pressure reading to the Desired Line Pressure reading on the scan tool. Does the Line Pressure stay within ± 34 kPa or 5 PSI of the Desired Line Pressure? No >> Go To 3 Yes >> Go To 5 3. CHECK LINE PRESSURE CONNECTOR AND WIRING Ignition on, engine not running. With the scan tool, monitor the Line Pressure Sensor voltage while wiggling the wiring harness and connectors Did the voltage remain steady while wiggling the wiring harness and connectors? Yes >> Go To 4 No >> Disconnect and properly reconnect the Line Pressure Sensor connector. Inspect terminals and repair as necessary. Perform 45RFE/545RFE TRANSMISSION VERIFICATION TEST - VER 1. 4. PCM AND WIRING Turn the ignition off to the lock position. Remove the Starter Relay. NOTE: Removal of the Starter Relay is to prevent a Transmission, NO RESPONSE, condition and disable the With the Transmission Simulator select the 9 OFF 9 position on the 9 Input/Output Speed 9 switch. Ignition on, engine not running. With the scan tool, monitor the Line Pressure during the following step. With the Transmission Simulator, turn the selector switch to each of the 3 Line Pressure positions. NOTE: All three scan tool Line Pressure readings should be steady and ±14 kPa or 2.0 PSI of the reading Does the Line Pressure on the scan tool fluctuate up and down more than 69 kPa or 10 PSI at any of the Yes >> Using the schematics as a guide, check the Powertrain Control Module (PCM) terminals for corrosion, damage, or terminal push out. Pay particular attention to all power and ground circuits. If no problems Perform 45RFE/545RFE TRANSMISSION VERIFICATION TEST - VER 1. No >> Repair internal transmission and inspect the oil pump per the Service information and replace if neces- sary. If no problems are found, replace the Transmission Solenoid/TRS Assembly — possible cause is Perform 45RFE/545RFE TRANSMISSION VERIFICATION TEST - VER 1. 21 - 604 AUTOMATIC TRANSMISSION 545RFE - ELECTRICAL DIAGNOSTICS ND |
