P136415 |
"C" Camshaft Position Actuator Bank 1 Circuit Short to Battery or Open |
While engine is running, open or short in VTM and VTP terminals of cam timing control motor with EDU assembly is detected for 3 seconds (1 trip detection logic). |

MONITOR DESCRIPTION
These DTCs are stored when a power supply malfunction, diagnostic signal malfunction or motor operation signal malfunction is detected in the cam timing control motor with EDU assembly. The cam timing control motor with EDU assembly is equipped with a self diagnostic function, which is used to send diagnostic a signal (VTM) to the ECM. If the ECM receives a VTP or VTM open or short signal, a DTC is output immediately (1 trip detection logic).

CAUTION / NOTICE / HINT
NOTICE:
Inspect the fuses for circuits related to this system before performing the following procedure.
HINT:
Read Freeze Frame Data using the GTS. The ECM records vehicle and driving condition information as Freeze Frame Data the moment a DTC is stored. When troubleshooting, Freeze Frame Data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.
