DTC Index

NOTE: If the control module or a component is suspect and the vehicle remains under manufacturer warranty, refer to the Warranty Policy and Procedures information or determine if any prior approval program is in operation, prior to the installation of a new module/component.

NOTE: Generic scan tools may not read the codes listed, or may read only five digit codes. Match the five digits from the scan tool to the first five digits of the seven digit code listed to identify the fault (the last two digits give extra information read by the manufacturer-approved diagnostic system).

NOTE: When performing electrical voltage or resistance tests, always use a digital multimeter (DMM) accurate to three decimal places, and with an up-to-date calibration certificate. When testing resistance, always take the resistance of the DMM leads into account.

NOTE: Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.

NOTE: If DTCs are recorded and, after the pinpoint tests have been carried out, the fault is not present, an intermittent concern may be the cause. Always check for loose connections and corroded terminals.

DTC	Description	Possible Cause	Action
P131500	Persistent misfire	ECM to ignition coil circuit fault Cylinder misfire DTCs also set Ignition coil failure Spark plug failure/fouled/incorrect gap Fuel delivery pressure low Fuel injector circuit faults Injector DTCs also set	Check for DTCs indicating an ignition or fuel related fault. Rectify as necessary.
P136700	Ignition spare	Ignition failure signal circuit: short circuit to ground Ignition failure signal circuit: open circuit Ignition failure signal circuit: short circuit to power Ignition coil failure	Check the ignition failure signal circuit. Refer to the electrical information. Rectify as necessary. Install a new coil as necessary. See IGNITION COIL-ON-PLUG .
P136800	Ignition spare	Ignition failure signal circuit: short circuit to ground Ignition failure signal circuit: open circuit Ignition failure signal circuit: short circuit to power Ignition coil failure	Check the ignition failure signal circuit. Refer to the electrical information. Rectify as necessary. Install a new coil as necessary. See IGNITION COIL-ON-PLUG .
