DTC P0098:00: Notes
DTC P0098:00 (L3 WITH TC) DETECTION CONDITION & POSSIBLE CAUSES
| DTC P0098:00 |
Boost air temperature sensor circuit high input |
| DETECTION CONDITION |
- If the PCM detects that the boost air temperature sensor voltage is 4.96 V or more
for 5 s
, the PCM determines that the boost air temperature sensor circuit voltage is high.
Diagnostic support note
- This is a continuous monitor (CCM).
- The MIL illuminates if the PCM detects the above malfunction condition during the first drive cycle.
- FREEZE FRAME DATA (Mode 2)/Snapshot data is available.
- The DTC is stored in the PCM memory.
|
| POSSIBLE CAUSE |
- MAP sensor/boost air temperature sensor connector or terminals malfunction
- Boost air temperature sensor malfunction
- PCM connector or terminals malfunction
- Short to power supply in wiring harness between the following terminals:
- MAP sensor/boost air temperature sensor terminal B-PCM terminal 2N
- MAP sensor/boost air temperature sensor terminal A-PCM terminal 2AV
- Open circuit in wiring harness between the following terminals:
- MAP sensor/boost air temperature sensor terminal B-PCM terminal 2N
- MAP sensor/boost air temperature sensor terminal A-PCM terminal 2AV
- PCM malfunction
