With Throttle Valve Actuator Only

DTC P1515

Current sensor circuit problem

DETECTION CONDITION
•  The PCM monitors the input voltage from the current sensor. If the input voltage is less than 0.24 V or more than 4.65 V, the PCM determines that there is a current sensor circuit problem.
Diagnostic support note
•  This is a continuous monitor (CCM).
•  The MIL does not illuminate.
•  PENDING CODE is available if the PCM detects the above malfunction condition.
•  FREEZE FRAME DATA is available.
•  The DTC is stored in the PCM memory.
POSSIBLE CAUSE
•  Current sensor malfunction
•  Connector or terminal malfunction
•  Open circuit in wiring harness between current sensor terminal A and PCM terminal 1AK
•  Short to ground in wiring harness between current sensor terminal A and PCM terminal 1AK
•  Open circuit in wiring harness between current sensor terminal C and PCM terminal 1AL
•  Short to power supply in wiring harness between current sensor terminal C and PCM terminal 1AL
•  Short to ground in wiring harness between current sensor terminal C and PCM terminal 1AL
•  Open circuit in wiring harness between current sensor terminal B and PCM terminal 1AG
•  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 SERVICE INFORMATION AVAILABILITY
•  Verify related Service Information availability.
•  Is any related Service Information available?
Yes
Perform repair or diagnosis according to the available Service InformationService Information.
•  If the vehicle is not repaired, go to the next step.
No
Go to the next step.
3
INSPECT CURRENT SENSOR CONNECTOR FOR POOR CONNECTION
•  Turn the ignition switch off.
•  Disconnect the current 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 CURRENT SENSOR CIRCUIT FOR SHORT TO GROUND
•  Turn the ignition switch off.
•  Inspect for continuity between the following terminals:
―  Current sensor terminal A (wiring harness-side) and body ground
―  Current sensor terminal C (wiring harness-side) and body ground
•  Is there continuity?
Yes
Repair or replace wiring harness for short to ground, then go to Step 9.
No
Go to the next step.
5
INSPECT CURRENT SENSOR CIRCUIT FOR SHORT TO POWER SUPPLY
•  Turn the ignition switch to the ON position (Engine off).
•  Measure the voltage between the current sensor terminal C (wiring harness-side) and body ground.
•  Is the voltage B+?
Yes
Repair or replace wiring harness for short to power supply, then go to Step 9.
No
Go to the next step.
6
INSPECT CURRENT SENSOR
•  Inspect the current sensor.
•  Is there any malfunction?
Yes
Replace the current sensor, then go to Step 9.
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 CURRENT SENSOR CIRCUIT FOR OPEN CIRCUIT
•  Turn the ignition switch off.
•  Inspect for continuity between the following terminals:
―  Current sensor terminal A (wiring harness-side) and PCM terminal 1AK (wiring harness-side)
―  Current sensor terminal C (wiring harness-side) and PCM terminal 1AL (wiring harness-side)
―  Current sensor terminal B (wiring harness-side) and PCM terminal 1AG (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 P1515 COMPLETED
•  Make sure to reconnect all disconnected connectors.
•  Clear the DTC from the PCM memory using the M-MDS.
•  Perform the KOEO/KOER self test.
•  Is the PENDING CODE same as the DTC present?
Yes
Replace the PCM, then go to the next step.
No
Go to the next step.
10
VERIFY AFTER REPAIR PROCEDURE
•  Perform the “AFTER REPAIR PROCEDURE”.
•  Are any DTCs present?
Yes
Go to the applicable DTC inspection.
No
DTC troubleshooting completed.
