DTC (PGM-FI)
- Problem verification 1
-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 0.50 V Do the current condition (s) match the threshold?
YES
The failure is duplicated. Go to step 3.
NO
Go to step 2.
- Problem verification 2
-1. Check the parameter (s) below with the HDS.
Signal Threshold Current conditions Values Unit Values Unit TP Sensor B More than 4.63 V Do the current condition (s) match the threshold?
YES
The failure is duplicated. Go to step 7.
NO
Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at the throttle body 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 (THL2 line, others)
-1. Check for Pending or Confirmed DTCs with the HDS.
DTC Description Confirmed DTC Pending DTC P0121 TP Sensor A Out of Range P0221 TP Sensor B Out of Range Are DTC P0121 and P0221 indicated at the same time?
YES
Go to step 5.
NO
Go to step 4.
- Shorted wire check (THL2 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 connectors.
PCM connector E (80P) Throttle body 6P connector -4. Measure the resistance between test points 1 and 2.
Test condition Vehicle OFF (LOCK) mode PCM connector E (80P) : disconnected Throttle body 6P connector: disconnected Test point 1 Throttle body 6P connector (female terminals) No. 4: Test point 2 Body ground Is there 1 MΩ or more?
YES
The THL2 wire is OK. Check for any authorized service information related to the DTCs or symptoms you are troubleshooting, or substitute a known-good PCM .
NO
Repair a short in the THL2 wire between the PCM (E51) and the throttle body.
- 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 point 1 Throttle body 6P connector (female terminals) No. 5: Test point 2 Body ground Is there about 5.0 V?
YES
NO
Go to step 6.
- Open wire check (VCC3 (DBW) 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. Measure the resistance between test points 1 and 2.
Test condition Vehicle OFF (LOCK) mode Throttle body 6P connector: disconnected PCM connector E (80P) : disconnected Test point 1 Throttle body 6P connector (female terminals) No. 5: Test point 2 PCM connector E (80P) No. 75 Is there 1.0 Ω or less?
YES
The VCC3 (DBW) wire is OK. Check for any authorized service information related to the DTCs or symptoms you are troubleshooting, or substitute a known-good PCM .
NO
Repair an open in the VCC3 (DBW) wire between the PCM (E75) and the throttle body.
- Determine possible failure area (SG3 (DBW) line, others)
-1. Check for Pending or Confirmed DTCs with the HDS.
DTC Description Confirmed DTC Pending DTC P0121 TP Sensor A Out of Range P0221 TP Sensor B Out of Range Are DTC P0121 and P0221 indicated at the same time?
YES
Go to step 10.
NO
Go to step 8.
- 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 point 1 Throttle body 6P connector (female terminals) No. 4: Test point 2 Body ground Is there about 5.0 V?
YES
NO
Go to step 9.
- Open wire check (THL2 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. Measure the resistance between test points 1 and 2.
Test condition Vehicle OFF (LOCK) mode Throttle body 6P connector: disconnected PCM connector E (80P) : disconnected Test point 1 Throttle body 6P connector (female terminals) No. 4: Test point 2 PCM connector E (80P) No. 51 Is there 1.0 Ω or less?
YES
The THL2 wire is OK. Check for any authorized service information related to the DTCs or symptoms you are troubleshooting, or substitute a known-good PCM .
NO
Repair an open in the THL2 wire between the PCM (E51) and the throttle body.
