DTC P1515:00 [MZR 1.3, MZR 1.5]

id0102f8706900

DTC P1515:00

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 4.89 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.
•  FREEZE FRAME DATA (Mode 2)/Snapshot data is not available.
•  The DTC is stored in the PCM memory.
POSSIBLE CAUSE
•  Current sensor connector or terminals malfunction
•  Short to ground in wiring harness between the following terminals:
―  Current sensor terminal A—PCM terminal 1AK
―  Current sensor terminal C—PCM terminal 1AL
•  PCM connector or terminals malfunction
•  Short to power supply in wiring harness between current sensor terminal C and PCM terminal 1AL
•  Current sensor circuits are shorted to each other
•  Open circuit in wiring harness between the following terminals:
―  Current sensor terminal A—PCM terminal 1AK
―  Current sensor terminal C—PCM terminal 1AL
―  Current sensor terminal B—PCM terminal 1AG
•  Current sensor malfunction
•  PCM malfunction

Diagnostic procedure

STEP

INSPECTION

ACTION
1
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 Information.
•  If the vehicle is not repaired, go to the next step.
No
Go to the next step.
2
INSPECT CURRENT SENSOR CONNECTOR CONDITION
•  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 connector and/or terminals, then go to Step 9.
No
Go to the next step.
3
INSPECT CURRENT SENSOR CIRCUIT FOR SHORT TO GROUND
•  Current sensor connector is disconnected.
•  Inspect for continuity between the following terminals (wiring harness-side) and body ground:
―  Current sensor terminal A
―  Current sensor terminal C
•  Is there continuity?
Yes
If the short to ground circuit could be detected:
•  Repair or replace the wiring harness for a possible short to ground.
If the short to ground circuit could not be detected:
•  Replace the PCM (short to ground in the PCM internal circuit).
Go to Step 9.
No
Go to the next step.
4
INSPECT PCM CONNECTOR CONDITION
•  Disconnect the PCM connector.
•  Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
•  Is there any malfunction?
Yes
Repair or replace the connector and/or terminals, then go to Step 9.
No
Go to the next step.
5
INSPECT CURRENT SENSOR SIGNAL CIRCUIT FOR SHORT TO POWER SUPPLY
•  Current sensor and PCM connectors are disconnected.
•  Turn the ignition switch to the ON position (engine off).
•  Measure the voltage at the current sensor terminal C (wiring harness-side).
•  Is there any voltage?
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 CURRENT SENSOR CIRCUITS FOR SHORT TO EACH OTHER
•  Current sensor and PCM connectors are disconnected.
•  Turn the ignition switch off.
•  Inspect for continuity between current sensor terminals A, C and B (wiring harness-side).
•  Is there continuity?
Yes
Repair or replace the wiring harness for a possible short to each other, then go to Step 9.
No
Go to the next step.
7
INSPECT CURRENT SENSOR CIRCUIT FOR OPEN CIRCUIT
•  Current sensor and PCM connectors are disconnected.
•  Inspect for continuity between the following terminals (wiring harness-side):
―  Current sensor terminal A—PCM terminal 1AK
―  Current sensor terminal C—PCM terminal 1AL
―  Current sensor terminal B—PCM terminal 1AG
•  Is there continuity?
Yes
Go to the next step.
No
Repair or replace the wiring harness for a possible open circuit, then go to Step 9.
8
INSPECT CURRENT SENSOR
•  Reconnect all disconnected connectors.
•  Inspect the current sensor.
•  Is there any malfunction?
Yes
Replace the current sensor, then go to the next step.
(See CURRENT SENSOR REMOVAL/INSTALLATION [MZR 1.3, MZR 1.5].)
No
Go to the next step.
9
VERIFY DTC TROUBLESHOOTING COMPLETED
•  Make sure to reconnect all disconnected connectors.
•  Clear the DTC from the PCM memory using the M-MDS.
•  Perform the KOEO or KOER self test.
•  Is the same DTC present?
Yes
Repeat the inspection from Step 1.
•  If the malfunction recurs, replace the PCM.
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.
(See DTC TABLE [MZR 1.3, MZR 1.5].)
No
DTC troubleshooting completed.
