| 204 - ELECTRICAL ROUTINE |
| Powertrain Control System |
|
- Electrical inputs/outputs, vehicle wiring harnesses, PCM, Mass Air Flow (MAF) sensor, Intake Air Temperature (IAT) sensor, Throttle Position (TP) sensor, Idle Speed Control (ISC), Power Steering Pressure (PSP) sensor, engine rpm, Line Pressure Control (LPC) solenoid, Transmission Fluid Temperature (TFT) sensor, Turbine Shaft Speed (TSS) sensor, Output Shaft Speed (OSS) sensor, Shift Solenoid A (SSA) or transaxle solenoid power control circuit open/shorted
|
|
| Solenoid Body |
|
- Incorrect solenoid body strategy data stored in the PCM
|
- Verify solenoid body strategy data stored in the PCM, download new identification and strategy as necessary. Refer to SOLENOID BODY STRATEGY .
|
| 304 - HYDRAULIC/MECHANICAL ROUTINE |
| Incorrect Pressures |
|
- Line pressure, LPC
pressure - high
|
- Carry out Line Pressure and Stall Speed Tests. Refer to SPECIAL TESTING PROCEDURES . Check pressure at line pressure taps. See the Line Pressure Chart for specifications. If high, check the Main Control Valve Body, Pump Assembly.
