    What Does P0347 Mean?

    The oxygen (02) sensors on your car measure the oxygen in the exhaust to determine how rich or lean the ratio of fuel and air are in the cylinders. Optimizing this mixture means better fuel economy and fewer exhaust emissions. When you see P0347 engine fault code on your engine code reader this description will help you.

    What are the common causes of P0347 ?

    The most common cause of this code is related to oil (or other engine fluids) that have leaked onto sensors, wiring, or electrical connectors. This typically causes grounded, broken, or shorted wiring, along with loose or shorted electrical connectors. In some cases fluid contamination has also caused camshaft sensors to go bad. Some vehicles will store a camshaft position sensor circuit code if the crankshaft sensor goes bad. If one or the other is found to be faulty; it is recommended that camshaft and crankshaft sensors be replaced as a set. PCM failure is also possible but rarely occurs.

    How do you troubleshoot P0347 ?

    Here are some of the repairs the mechanics might use when repairing the P0347 code.
    • Check the battery’s
    • Check the wiring that runs to the starter and make repairs to it as needed, since corrosion and loose connections are common
    • Replace the starter
    • Check the connector that’s on the camshaft sensor
    • Replace the CPS, or camshaft position sensor
