DTC P0098-00: IAT Sensor No. 2 Circuit High Input: Notes
DTC P0098:00 (PCM, SKYACTIV-G 2.5T) DETECTION CONDITION AND POSSIBLE CAUSE
| DTC P0098:00 |
IAT sensor No. 2 circuit high input |
| DETECTION CONDITION |
- If the PCM detects that the IAT sensor No. 2 voltage at the PCM terminal 1BN is 4.96 V or more for 5 s, the PCM determines that the IAT sensor No. 2 circuit voltage is high.
Diagnostic support note
- This is a continuous monitor (CCM).
- The check engine light illuminates if the PCM detects the above malfunction condition during the first drive cycle.
- FREEZE FRAME DATA/Snapshot data is available.
- DTC is stored in the PCM memory.
