DTC P0198-00: Engine Oil Temperature Sensor Circuit High Input: Notes
DTC P0198:00 PCM (SKYACTIV-G 2.5 - WITH CYLINDER DEACTIVATION) DETECTION CONDITION AND POSSIBLE CAUSE
| DTC P0198:00 |
Engine Oil Temperature Sensor Circuit High Input |
| DETECTION CONDITION |
- The PCM monitors the engine oil temperature sensor signal. If the PCM detects that the engine oil temperature sensor voltage at the PCM terminal 1AN is above 4.95 V for 4 s, the PCM determines that the engine oil temperature sensor circuit has a malfunction.
MONITORING CONDITIONS
- Battery voltage: 8-20 V
- 5 s have elapsed after the ignition was switched ON (engine off or on)
Diagnostic support note
- This is a continuous monitor (CCM).
- The check engine light does not illuminate.
- FREEZE FRAME DATA is not available.
- Snapshot data is available.
- DTC is stored in the PCM memory.

| FAIL-SAFE FUNCTION |
|
| POSSIBLE CAUSE |
- Engine oil pressure sensor/engine oil temperature sensor connector or terminals malfunction
- PCM connector or terminals malfunction
- Short to power supply in wiring harness between engine oil pressure sensor/engine oil temperature sensor terminal E and PCM terminal 1AN
- Open circuit in wiring harness between the following terminals:
- Engine oil pressure sensor/engine oil temperature sensor terminal E-PCM terminal 1AN
- Engine oil pressure sensor/engine oil temperature sensor terminal C-PCM terminal 1AB
- Engine oil temperature sensor malfunction
- PCM malfunction
