C3412 Renault Clio OBD Code

OBD/2 C3412 error code description and symptoms.

Low Speed Fuel Pump Primary Circuit Malfunction The PCM monitors the low speed fuel pump (LFP) primary circuit output from the PCM.
The test fails if: When the LFP circuit is commanded on (grounded), excessive current draw is detected on the LFP circuit; or when the LFP circuit is commanded off, voltage is not detected on the LFP circuit (the PCM expects to detect VPWR voltage coming through the low speed fuel pump relay coil to the LFP circuit). Open or shorted low fuel pump (LFP) circuit Open VPWR to low speed fuel pump relay Damaged low speed fuel pump relay Damaged PCM An open circuit or short to ground can only be detected with the low speed fuel pump.

As the engine heats up and combustion becomes easier and more complete, the PCM will command the idling control valve to increase the amount of air entering the engine to suit the changing conditions. However, when the load on the engine changes, say, when some electrical consumers or other systems are either turned on or off, the PCM adapts the signal voltage to the idle control valve to ensure that the idling speed remains stable, and at the RPM specified by the manufacturer.

C3412 Renault Clio Error Code Repair Process :

If your seat switch reference voltage positive common supply voltage fault check engine light is illuminated, it's best to take it in for diagnostic testing, which can feel like a hassle. Because while the lights vary in appearance from vehicle to vehicle, all have the same basic meaning: There's a problem with the car's emissions system. The on-board diagnostics system C3412 and engine control unit are in charge of monitoring a bunch of different seat switch reference voltage positive common supply voltage fault, and if they get a reading that's a little out of whack, up pops the check engine light.

Common Causes of Renault Clio C3412 OBD2 Code

A common cause of code C3412 is the failure of Seat Switch Reference Voltage Positive Common Supply Voltage Fault, but there are several other possible causes as well, such as ;

EVAP canister or fuel tank leaks
Faulty front heated oxygen sensor
Failures of clutch motion/travel sensors.
Variable Valve Timing (VVT) circuit is open or shorted

C3412 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.
