DTC P2135

DTC P2135  : TP Sensor A/B Incorrect Voltage Correlation

NOTE:  Before you troubleshoot, review the general troubleshooting information .

DTC (PGM-FI)

1. Problem verification

   -1. Turn the vehicle to the ON mode.

   -2. Clear the DTC with the HDS.

   -3. Select the ETCS (TAC) TEST in the Function Test Menu with the HDS.

   ETCS (TAC) TEST

   Check for Pending or Confirmed DTCs with the HDS.

   DTC Description	Confirmed DTC	Pending DTC
   P2135 TP Sensor A/B Incorrect Voltage Correlation

   Is DTC P2135 indicated?

   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. If the on-board snapshot of this DTC is recorded, try to reproduce the failure under the same conditions with the on-board snapshot .

2. Determine possible failure area (PCM, others)

   -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
   	PCM connector E (80P): disconnected
   Test point 1	PCM connector E (80P) No. 50
   Test point 2	PCM connector E (80P) No. 51

   Is there 1 MΩ or more?

   YES 

   Check for any authorized service information related to the DTCs or symptoms you are troubleshooting, or substitute a known-good PCM .

   NO 

   Go to step 3.

3. Shorted wire check (THL1 line to THL2 line)

   -1. Disconnect the following connector.

   Throttle body 6P connector

   -2. 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	PCM connector E (80P) No. 50
   Test point 2	PCM connector E (80P) No. 51

   Is there 1 MΩ or more?

   YES 

   The THL1 wire and the THL2 wire are OK. Replace the throttle body .

   NO 

   Repair a short in the THL1 wire to the THL2 wire between the PCM (E50, E51) and the throttle body.
