Renault Fault Codes

Renault is a French automobile manufacturer that works closely with Japanese automaker Nissan. You will most likely find that the error codes that are more common in Nissan cars also make more appearances than others in Renault models too.

Some of the most common Renault fault codes are those that are to do with the delivery of fuel and air to the engine as well as removing the exhaust gases.

One of the most common codes is the P0299, which is a sign that that turbocharger or supercharger is not producing enough boost. This can be down to the component not being able to work due to a build of grime. It may also be caused by a problem with the sensor itself or the wires/connections attached to it.

Another common Renault fault code is the P0089 and this one is concerning the fuel injection system. The reason that this is a common code usually stems from the fact that (like the P0299 code mentioned above) the injectors can become overloaded with dirt, restricting their ability to work. Alongside this being the cause it can also be a sign that the lines that carry the fuel from the pump have become clogged before or after the fuel filter.

According to feedback from our visitors, you may also find the P1493 error code appearing in your Renault. This sensor is located in the engine bay near the battery and is prone to attacks from wild animals getting underneath the bonnet. Check to see if the connections are secure and if the wiring has been damaged – both easily fixable yourself at home.

After the engine and moving toward the exhaust in Renault cars you find the DPF (diesel particulate filter), a component that helps filter out some of the dirtiest elements in the exhaust gases. If this becomes clogged in your Renault then you may see the P2002 error code appear on an ODB2 reader. This could in fact be caused by a faulty sensor that reads the oxygen levels of the gases after the DPF, something that can easily be tested by a trained mechanic. The DPF flushes itself during long drives – too many short journeys can be the cause of this error.
