DTC P2185:00: Notes
DTC P2185:00 (MZR 1.5) DETECTION CONDITION AND POSSIBLE CAUSES
| DTC P2185:00 |
ECT sensor No. 2 circuit high input |
| DETECTION CONDITION |
- The PCM monitors the ECT sensor No. 2 signal. If the PCM detects that the ECT sensor No. 2 voltage is above 4.92 V
for 5 s
, the PCM determines that the ECT sensor No. 2 circuit has a malfunction.
Diagnostic support note
- This is a continuous monitor (engine cooling system).
- 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 |
- ECT sensor No. 2 connector or terminals malfunction
- ECT sensor No. 2 malfunction
- PCM connector or terminals malfunction
- Short to power supply in wiring harness between ECT sensor No. 2 terminal A and PCM terminal 1Y
- Open circuit in wiring harness between the following terminals:
- ECT sensor No. 2 terminal A-PCM terminal 1Y
- ECT sensor No. 2 terminal B-PCM terminal 1U
- PCM malfunction
