Determine possible failure area (THL2 line, others):
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.
3.
Shorted wire check (THL2 line):
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 point 1
Throttle body 6P connector No. 4
Test point 2
Body ground
Is there continuity?
YES
Repair a short in the THL2 wire between the PCM (B47) and the throttle body.?
NO
The THL2 wire is OK. Update the PCM if it does not have the latest software, or substitute a known-good PCM, then recheck. If DTC P0222 goes away and the PCM was updated, troubleshooting is complete. If DTC P0222 goes away and the PCM was substituted, replace the original PCM.?
4.
Determine possible failure area (VCC3 line, throttle body):
Determine possible failure area (VCC3 line, throttle body)
The VCC3 wire is OK. Update the PCM if it does not have the latest software, or substitute a known-good PCM, then recheck. If DTC P0222 goes away and the PCM was updated, troubleshooting is complete. If DTC P0222 goes away and the PCM was substituted, replace the original PCM.?
NO
Repair an open in the VCC3 wire between the PCM (B48) and the throttle body.?
