DTC P2135: Throttle Position Sensor (main and sub) Range/Performance Problem
 
 
 
 
THROTTLE POSITION SENSOR (main and sub) RANGE/PERFORMANCE PROBLEM CIRCUIT
Refer to DTC P0122 - Throttle Position Sensor (main) Circuit Low Input , DTC P0222 - Throttle Position Sensor (sub) Circuit Low Input .
 
 
CIRCUIT OPERATION
Refer to DTC P0122 - Throttle Position Sensor (main) Circuit Low Input , DTC P0222 - Throttle Position Sensor (sub) Circuit Low Input .
 
 
TECHNICAL DESCRIPTION
  • ECM checks the throttle position sensor output signal characteristics for abnormal conditions.
 
 
DESCRIPTIONS OF MONITOR METHODS
  • Detect malfunction if the relation between throttle position sensor (main) and throttle position sensor (sub) is wrong.
 
 
MONITOR EXECUTION
  • Continuous
 
 
MONITOR EXECUTION CONDITIONS (Other monitor and Sensor)
Other Monitor (There is no temporary DTC set in memory for the item monitored below)
  • Not applicable
Sensor (The sensor below is determined to be normal)
  • Not applicable
 
 
DTC SET CONDITIONS <Range/Performance problem-relation between main and sub>
Logic Flow Chart
Check Conditions
  • The target output voltage of the throttle position sensor is 0.9 volt or less.
  • Throttle position sensor (main) output voltage is between 0.2 and 4.8 volts.
  • Throttle position sensor (sub) output voltage is between 0.2 and 4.8 volts.
  • Battery positive voltage is higher than 8.3 volts.
Judgment Criterion
  • The difference between V1 and V2 is more than 0.3 volt for 0.3 second.
    • V1: Throttle position sensor (main) output voltage
    • V2: Throttle position sensor (sub) output voltage subtracted from 5 volts
Logic Flow Chart
Check Conditions
  • Throttle position sensor (main) output voltage is between 0.2 and 4.8 volts.
  • Throttle position sensor (sub) output voltage is between 0.2 and 4.8 volts.
Judgment Criterion
  • For 0.3 second, the sum of the output voltage of the throttle position sensors (main) and (sub) is less than 4.5 volts, or more than 5.5 volts.
 
 
FAIL-SAFE AND BACKUP FUNCTION
  • Throttle opening degree position is in default position.
 
 
OBD-II DRIVE CYCLE PATTERN
  • Refer to Diagnostic Function - OBD-II Drive Cycle - Pattern 1 .
 
 
TROUBLESHOOTING HINTS (The most likely causes for this code to be set are: )
  • Throttle position sensor failed.
  • Throttle position sensor circuit harness damage, or connector damage.
  • ECM failed.

 
 
DIAGNOSIS
STEP 1. Check the continuity at throttle body assembly harness side connector.
(1) Disconnect the throttle body assembly connector and measure at the harness side.
(2) Check for the continuity between terminal TPSE and ground.
  • Continuity (2 ohms or less)
Does continuity exist?
Go to Step 4.
Go to Step 2.
 
STEP 2. Check of harness damage in TPSE line between throttle body assembly connector and ECM connector.
Is the harness wire in good condition?
Go to Step 3.
Repair the connector(s) or wiring harness. Then go to Step 8.
 
STEP 3. Check the trouble symptoms.
(1) Carry out a test drive with the drive cycle pattern. Refer to Diagnostic Function - OBD-II Drive Cycle - Pattern 1 .
(2) Check the diagnostic trouble code (DTC).
Is DTC P2135 set?
Replace the ECM (Refer to, Removal and Installation ). Then go to Step 8.
It can be assumed that this malfunction is intermittent. Refer to GROUP 00, How to Use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunctions .
 
STEP 4. Check of harness damage TPS5 line between throttle body assembly connector and ECM connector.
Is the harness wire in good condition?
Go to Step 5.
Repair the connector(s) or wiring harness. Then go to Step 8.
 
STEP 5. Check of harness damage in TPSM line between throttle body assembly connector and ECM connector.
Is the harness wire in good condition?
Go to Step 6.
Repair the connector(s) or wiring harness. Then go to Step 8.
 
STEP 6. Check of harness damage in TPSS line between throttle body assembly connector and ECM connector.
Is the harness wire in good condition?
Go to Step 7.
Repair the connector(s) or wiring harness. Then go to Step 8.
 
STEP 7. Replace the throttle body assembly.
(1) Replace the throttle body assembly.
(2) Carry out a test drive with the drive cycle pattern. Refer to Diagnostic Function - OBD-II Drive Cycle - Pattern 1 .
(3) Check the diagnostic trouble code (DTC).
Is DTC P2135 set?
Replace the ECM (Refer to, Removal and Installation ). Then go to Step 8.
The inspection is complete.
 
STEP 8. Test the OBD-II drive cycle.
(1) Carry out a test drive with the drive cycle pattern. Refer to Diagnostic Function - OBD-II Drive Cycle - Pattern 1 .
(2) Check the diagnostic trouble code (DTC).
Is DTC P2135 set?
Retry the troubleshooting.
The inspection is complete.
