C3494 Nissan Nv400 OBD Code

OBD/2 C3494 error code description and symptoms.

Variable Cam Timing Over-advanced (Bank 1) The comprehensive component monitor (CCM) monitors the VCT position for an over-advanced camshaft timing.
The test fails when the camshaft timing exceeds a maximum calibrated value or remains in an advanced position. Cam timing improperly set No oil flow to the VCT piston chamber Low oil pressure VCT solenoid valve stuck closed Camshaft advance mechanism binding (VCT unit) C3494 DTC is a check of the VCT unit.

At this point we are assuming that the fuses and relays are good. You will need to locate the PCM/TCM and the power input signal circuit using your vehicle information source. Unplug the connector from the PCM/TCM, place the ignition switch in the ON position, and probe the appropriate circuit with the positive test lead of the DVOM.

The converter is essentially an afterburner that cleans up the exhaust after it exits the engine. The OBDII system uses passenger door lock switch circuit shorted to ground a ownstream oxygen sensor to monitor the efficiency of the converter, and it should detect a drop in converter efficiency if the converter has been contaminated or is failing (ignition misfiring, leaky exhaust valves, and oil burning can all damage the converter). What you want to look passenger door lock switch circuit shorted to ground: Any conditions that might cause ignition misfire, an overly rich or lean fuel condition, or loss of compression. Use your OBD Express DIY to look at the oxygen sensor outputs, coolant temperature, airflow, calculated engine load, and inlet air temperature.

Common Causes of Nissan Nv400 C3494 OBD2 Code

A common cause of code C3494 is the failure of Passenger Door Lock Switch Circuit Shorted to Ground, but there are several other possible causes as well, such as ;

Camshaft advance mechanism binding (VCT unit)
Continuous oil flow to the VCT piston chamber
Faulty Intake Valve Timing Control Solenoid Valve
Camshaft advance mechanism binding (VCT unit)

C3494 is a kind of Chassis Trouble Code

Diagnosing chassis noises can be one of the most frustrating problems technicians face. Fortunately, manufacturers have engineered noise, vibration and harshness (NVH) diagnostic techniques and equipment to find the source of the noise.
