| 256 - ROUTINE |
| Powertrain Control System |
- CARRY OUT On-Board Diagnostic (OBD) tests. REFER to the
INTRODUCTION
article for diagnosis and testing of the PCM, APP
sensor, ECT
sensor and IAT
sensor. For diagnosing TCC
solenoid, GO to PINPOINT TEST A . For diagnosing TFT
sensor, GO to PINPOINT TEST B . For diagnosing OSS
sensor, GO to PINPOINT TEST D . REPAIR as necessary. CLEAR the DTCs, ROAD TEST the vehicle and RERUN the OBD
test.
