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 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 A and PCM terminal 1AK
• Short to power supply 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 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 REPAIR INFORMATION AVAILABILITY
• Verify related service 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 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 C (wiring harness-side) and body ground
- Current sensor terminal A (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 A (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 C (wiring harness-side) and PCM terminal 1AL (wiring harness-side)
- Current sensor terminal A (wiring harness-side) and PCM terminal 1AK (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 WDS or equivalent.
• 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.
