C2128 Mitsubishi Se-ro OBD Code

OBD/2 C2128 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.

As long as the throttle plate remains closed, the idling speed and quality is controlled by the PCM via the idle control valve, and as can be seen from the above it should be clear that idle control on a gasoline engine is a complex affair. For instance, if the engine is started in sub-zero temperatures, the PCM will command the idling control valve to allow less air to enter the engine to enrich the air/fuel mixture to create a condition which is roughly analogous to how chokes worked on carburetted engines to control idling in cold weather.

If your fuel pump low speed malfunction 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 C2128 and engine control unit are in charge of monitoring a bunch of different fuel pump low speed malfunction, and if they get a reading that's a little out of whack, up pops the check engine light.

Common Causes of Mitsubishi Se-ro C2128 OBD2 Code

A common cause of code C2128 is the failure of Fuel Pump Low Speed Malfunction, but there are several other possible causes as well, such as ;

Dirty Oil
Air fuel ratio (A/F) Sensor 1 Bank 1 circuit poor electrical connection
Foreign matter caught in fuel filler cap
Oil flow restriction in the oil passages or the variable camshaft timing (VCT) valve body

C2128 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.
