P0342 Camshaft Position Sensor "A" Circuit Low (Bank 1 or Single Sensor)

Engine timing

P0342 means the camshaft position sensor's signal is too low, usually wiring or a failed sensor.

The camshaft position sensor's signal voltage is too low, usually from an open or shorted wire or a failed sensor.

Can I keep driving? Yes, but get it fixed soon.

Many engines still run using the crank sensor, but may start slowly or run poorly. Get it fixed soon.

Common causes

  1. A failed camshaft position sensor
  2. An open or shorted signal wire
  3. A missing 5-volt reference or ground
  4. Oil in the connector

Symptoms

  • Hard or long starting
  • Rough running

What to check first

  1. Check the connector for oil and corrosion.
  2. Check the sensor's power, ground and signal as your service information describes.
  3. Repair wiring if needed, then replace the sensor if power and ground are good.
