| P0222 TP Sensor B Circuit Low Voltage |
DTC (PGM-FI)
- Problem verification
-1. Turn the vehicle to the ON mode.
-2. Clear the DTC with the HDS.
-3. Check the parameter(s) below with the HDS.
Signal Threshold Current conditions Values Unit Values Unit TP SENSOR B Less than 0.3 V Do the current condition(s) match the threshold?
YES
The failure is duplicated. Go to step 2.
NO
Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at the throttle body and the PCM.
- Determine possible failure area (THL2 line, others)
-1. Check for Pending or Confirmed DTCs with the HDS.
DTC Description Confirmed DTC Pending DTC Freeze Frame P0122 TP Sensor A Circuit Low Voltage P0222 TP Sensor B Circuit Low Voltage Are DTC P0122 and P0222 indicated at the same time?
YES
Go to step 4.
NO
Go to step 3.
- Shorted wire check (THL2 line)
-1. Turn the vehicle to the OFF (LOCK) mode.
-2. Jump the SCS line with the HDS.
-3. Disconnect the following connectors.
PCM connector B (51P) Throttle body 6P connector -4. Check for continuity between test points 1 and 2.
Test condition
Vehicle OFF (LOCK) mode PCM connector B (51P): disconnected Throttle body 6P connector: disconnected Test circuit THL2 Test point 1 Throttle body 6P connector No. 4 (TAN) Test point 2 Body ground Is there continuity?
YES
Repair a short in the THL2 wire between the PCM (B40) and the throttle body, then do the repair verification.
NO
The THL2 wire is OK. Update the PCM if it does not have the latest software, or substitute a known-good PCM , then do the repair verification.
- Determine possible failure area (throttle body, others)
-1. Turn the vehicle to the OFF (LOCK) mode.
-2. Disconnect the following connector.
Throttle body 6P connector -3. Turn the vehicle to the ON mode.
-4. Measure the voltage between test points 1 and 2.
Test condition
Vehicle ON mode Throttle body 6P connector: disconnected Test circuit VCC5 Test point 1 Throttle body 6P connector No. 5 (BLU) Test point 2 Body ground Is there about 5.0 V?
YES
Replace the throttle body , then do the repair verification.
NO
Go to step 5.
- Open wire check (VCC5 line)
-1. Turn the vehicle to the OFF (LOCK) mode.
-2. Jump the SCS line with the HDS.
-3. Disconnect the following connector.
PCM connector B (51P) -4. Check for continuity between test points 1 and 2.
Test condition
Vehicle OFF (LOCK) mode Throttle body 6P connector: disconnected PCM connector B (51P): disconnected Test circuit VCC5 Test point 1 Throttle body 6P connector No. 5 (BLU) Test point 2 PCM connector B (51P) No. 44 (BLU) Is there continuity?
YES
The VCC5 wire is OK. Update the PCM if it does not have the latest software, or substitute a known-good PCM , then do the repair verification.
NO
Repair an open in the VCC5 wire between the PCM (B44) and the throttle body, then do the repair verification.
- Repair verification
-1. Turn the vehicle to the OFF (LOCK) mode.
-2. Reconnect all connectors.
-3. Exit the SCS mode with the HDS.
-4. Turn the vehicle to the ON mode.
-5. Reset the PCM with the HDS .
Reset PCM
-6. Do the PCM idle learn procedure.
-7. Check for Pending or Confirmed DTCs with the HDS.
DTC Description Confirmed DTC Pending DTC Freeze Frame P0222 TP Sensor B Circuit Low Voltage DTC (PGM-FI)
Is DTC P0222 indicated?
YES
Check for poor connections or loose terminals at the throttle body and the PCM. If the PCM was updated, substitute a known-good PCM , then recheck. If the PCM was substituted, go to step 1.
NO
Troubleshooting is complete. If the PCM was substituted, replace the original PCM . If any other Pending or Confirmed DTCs are indicated, go to the indicated DTC's troubleshooting.
