C1302 Renault 21 OBD Code

OBD/2 C1302 error code description and symptoms.

Catalytic converters must be warm before they can work properly. On a cold start the PCM provides a rich mixture to keep the cold engine running.
All that extra fuel goes into the catalytic converter. But the exhaust isn't very hot, because, ah, the engine is pretty cold. GM has employed several strategies to fire up the catalytic converter quicker and reduce cold start emissions. One way is to use a secondary air pump that pumps outside air directly into the catalytic converter.

Circuit High Input codes like C1302 are mostly caused by defective alternators that develop excessive voltages, although there may be other causes as well, such as short circuits that 'leak' current into a particular system from other, unrelated systems that work on higher voltages. Note that in the case of short circuits that leak power into a control circuit, there is likely to be other, seemingly unrelated trouble codes present along with the code(s) being investigated. Diagnosing a 'high input' code will always involve a thorough testing of the charging system as a first step, followed by measures to isolate the system from all other possible sources of power during resistance, continuity, and reference voltage tests.

For vaps solenoid actuator output circuit open check engine light is perhaps the most troubling of lights because it could mean so many different things, from you didn't screw the gas cap on tightly enough to look out for pistons flying through the hood and into the stratosphere. The easiest way to find out what this light is telling you is to hook your vehicle up to a scan tool.

After you instruct it to perform the scan, it speaks vaps solenoid actuator output circuit open with your car's computers to find out exactly what's prompting the light to turn on.

Common Causes of Renault 21 C1302 OBD2 Code

A common cause of code C1302 is the failure of VAPS Solenoid Actuator Output Circuit Open, but there are several other possible causes as well, such as ;

Dirty Oil
Erratic camshaft position due to low oil pressure
Continuous oil flow to the VCT piston chamber
EVAP canister or fuel tank leaks

C1302 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.
