DTC P0335 [13B-MSP]

DTC REFERENCE CHART

DTC P0335 Eccentric shaft position sensor circuit problem
DETECTION CONDITION 
  • The PCM monitors the input signal from the eccentric shaft position sensor when the mass intake airflow amount is more than 2 g/s {0.26 lb/min}  . If the input signal is not input, the PCM determines that there is an eccentric shaft position sensor circuit malfunction.

Diagnostic support note 

  • This is a continuous monitor (CCM.)
  • The MIL illuminates if the PCM detects the above malfunction condition in the first drive cycle.
  • FREEZE FRAME DATA is available.
  • The DTC is stored in the PCM memory.
POSSIBLE CAUSE 
  • Connector or terminal malfunction
  • Short to ground in wiring harness between eccentric shaft position sensor terminal A and PCM terminal 2AG
  • Short to ground in wiring harness between eccentric shaft position sensor terminal B and PCM terminal 2AP
  • Short to power supply in wiring harness between eccentric shaft position sensor terminal A and PCM terminal 2AG
  • Short to power supply in wiring harness between eccentric shaft position sensor terminal B and PCM terminal 2AP
  • Eccentric shaft position sensor is dirty
  • Eccentric shaft position sensor malfunction
  • Open circuit in wiring harness between eccentric shaft position sensor terminal A and PCM terminal 2AG
  • Open circuit in wiring harness between eccentric shaft position sensor terminal B and PCM terminal 2AP
  • PCM malfunction

DIAGNOSTIC PROCEDURE

STEP INSPECTION ACTION
1 VERIFY FREEZE FRAME DATA HAS BEEN RECORDED 
  • Has FREEZE FRAME DATA been recorded?
 Yes Go to the next step.
No Record the FREEZE FRAME DATA on the repair order, then go to the next step.
2 VERIFY RELATED REPAIR INFORMATION AVAILABILITY 
  • Verify related Service Bulletins and/or on-line repair information availability.
  • Is any related repair information available?
 Yes Perform repair or diagnosis according to the available repair information.
  • If the vehicle is not repaired, go to the next step.
No Go to the next step.
3 INSPECT ECCENTRIC SHAFT POSITION SENSOR CONNECTOR FOR POOR CONNECTION 
  • Turn the ignition switch off.
  • Disconnect the eccentric shaft position sensor connector.
  • Inspect for poor connection (such as damaged/pulled-out pins, corrosion.)
  • Is there any malfunction?
 Yes Repair or replace the terminal, then go to Step 9.
No Go to the next step.
4 INSPECT ECCENTRIC SHAFT POSITION SENSOR CIRCUIT FOR SHORT TO GROUND 
  • Turn the ignition switch off.
  • Inspect for continuity between the following circuits:
    • Eccentric shaft position sensor terminal A (wiring harness-side) and body ground
    • Eccentric shaft position sensor terminal B (wiring harness-side) and body ground
  • Is there continuity?
 Yes Repair or replace the wiring harness for a possible short to ground, then go to Step 9.
No Go to the next step.
5 INSPECT ECCENTRIC SHAFT POSITION SENSOR CIRCUIT FOR SHORT TO POWER SUPPLY 
  • Turn the ignition switch to the ON position (engine off.)
  • Measure the voltage between the following circuits:
    • Eccentric shaft position sensor terminal A (wiring harness-side) and body ground
    • Eccentric shaft position sensor terminal B (wiring harness-side) and body ground
  • Is the voltage B+  ?
 Yes Repair or replace the wiring harness for a possible short to power supply, then go to Step 9.
No Go to the next step.
6 INSPECT ECCENTRIC SHAFT POSITION SENSOR  Yes Replace the eccentric shaft position sensor, then go to Step 9. (See ECCENTRIC SHAFT POSITION SENSOR REMOVAL/INSTALLATION [13B-MSP] .)
No Go to the next step.
7 INSPECT PCM CONNECTOR FOR POOR CONNECTION 
  • Turn the ignition switch off.
  • Disconnect the PCM connector.
  • Inspect for poor connection (such as damaged/pulled-out pins, corrosion.)
  • Is there any malfunction?
 Yes Repair or replace the terminal, then go to Step 9.
No Go to the next step.
8 INSPECT ECCENTRIC SHAFT POSITION SENSOR CIRCUIT FOR OPEN CIRCUIT 
  • Turn the ignition switch off.
  • Inspect for continuity between the following circuits:
    • Eccentric shaft position sensor terminal A (wiring harness-side) and PCM terminal 2AG (wiring harness-side)
    • Eccentric shaft position sensor terminal B (wiring harness-side) and PCM terminal 2AP (wiring harness-side)
  • Is there continuity?
 Yes Go to the next step.
No Repair or replace the wiring harness for a possible open circuit, then go to the next step.
9 VERIFY TROUBLESHOOTING OF DTC P0335 COMPLETED 
  • Make sure to reconnect all disconnected connectors.
  • Clear the DTC from the PCM memory using the M-MDS.
  • Start the engine and run the engine for 5 s or more  .
  • Is the same DTC present?
 Yes Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [13B-MSP] .)
No Go to the next step.
10 VERIFY AFTER REPAIR PROCEDURE  Yes Go to the applicable DTC inspection. (See DTC TABLE [13B-MSP] .)
No DTC troubleshooting completed.
