| P2184 ECT Sensor 2 Circuit Low Voltage |
DTC (PGM-FI)
- Problem verification
-1. Turn the vehicle to the ON mode.
-2. Check the parameter (s) below with the HDS.
Signal Threshold Current conditions Values Unit Values Unit ECT Sensor 2 Voltage 0.08 or less V Do the current condition (s) match the threshold?
YES
Go to step 2.
NO
Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at ECT sensor 2 and the PCM. If the on-board snapshot of this DTC is recorded, try to reproduce the failure under the same conditions with the on-board snapshot .
- Determine possible failure area (ECT sensor 2, others)
-1. Turn the vehicle to the OFF (LOCK) mode.
-2. Disconnect the following connector.
ECT Sensor 2 2P connector -3. Turn the vehicle to the ON mode.
-4. Check the parameter (s) below with the HDS.
Signal Threshold Current conditions Values Unit Values Unit ECT Sensor 2 Voltage 0.08 or less V Do the current condition (s) match the threshold?
YES
Go to step 3.
NO
- Shorted wire check (TW2/TW2 SENSOR line)
-1. Turn the vehicle to the OFF (LOCK) mode.
-2. Jump the SCS line with the HDS, and wait more than 1 minute.
-3. Disconnect the following connector.
PCM connector E (80P) -4. Check for continuity between test points 1 and 2.
Test condition Vehicle OFF (LOCK) mode ECT Sensor 2 2P connector: disconnected PCM connector E (80P): disconnected Test point 1 ECT sensor 2 2P connector (female terminals) No. 2: Test point 2 Body ground Is there continuity?
YES
Repair a short in the TW2/TW2 SENSOR wire between the PCM (E54) and ECT sensor 2.
NO
The TW2/TW2 SENSOR wire is OK. Check for any authorized service information related to the DTCs or symptoms you are troubleshooting, or substitute a known-good PCM .
