Your powertrain control module (PCM) receives signals from various sensors and switches all over your vehicle. It helps your vehicle perform at its best. However, it can have issues due to component complications or malfunctions. These problems can cause irregularities in the signals being sent to your PCM, which may trigger it to set trouble codes, such as code P0342.

Did a P0342 code show up after using a scan tool on your vehicle? Here are the basic information you need to know about a P0342 code:

What Does the P0342 Code Mean?

P0342 is a diagnostic trouble code (DTC) that stands for “Camshaft Position Sensor ‘A’ Circuit Low.” It basically means that your PCM is not detecting a correct signal from your camshaft position sensor.

Toyota, for example, describes code P0342 as: “The output voltage of the camshaft position sensor is less than 0.3 V for 4 seconds.”

Designation “A” refers to the sensor located in Bank 1, which has your engine’s cylinder #1. Your camshaft position sensors send information to your PCM so it can optimally operate your fuel injectors, spark plugs, and ignition coils. If there are issues causing weak or irregular camshaft position sensor signals, your PCM can trigger a P0342 code to notify you about the complication.
