C0670 Renault P55 OBD Code

OBD/2 C0670 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) C0670 DTC is a check of the VCT unit.

Some systems require that the actuator has an adequate supply of brake fluid. Low brake fluid levels can mimic the symptoms of code C0670, so consult the manual to locate the brake fluid reservoir. Bear in mind that a low fluid level can set code C0670 on some applications, so make sure that on fluid operated systems the fluid level is up to the mark before starting an electrical diagnosis.

C0670 Renault P55 Error Code Repair Process :

If your vehicle failed a C0670 test and the C0670 Check Engine Light is NOT on, chances are you have a problem with the OBDII system, a burned out MIL lamp, or a faulty catalytic converter. The converter is essentially an afterburner that cleans up the exhaust after it exits the engine. The OBDII system uses mirror switch reference voltage negative common open circuit 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 mirror switch reference voltage negative common open circuit: 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 Renault P55 C0670 OBD2 Code

A common cause of code C0670 is the failure of Mirror Switch Reference Voltage Negative Common Open Circuit, but there are several other possible causes as well, such as ;

Camshaft advance mechanism binding (VCT unit)
EVAP canister or fuel tank leaks
Ignition coils circuit poor electrical connection
Improper ignition timing

C0670 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.
