Symptoms

Common symptoms of bad Mazda crankshaft position sensor include:

  • Mazda won't start
  • Intermittent Starting
  • Check Engine Light On
  • Mazda cranks but won't start.
  • Engine idles rough
  • Fault Codes: P0335, P0017, P0016

These symptoms may be intermittent in some cases. That's why it makes it hard to diagnose a bad crankshaft position sensor, especially if the check engine light has not turned on.

Follow these steps to change the crankshaft position sensor on a Mazda.

You will need

  • Mazda Crankshaft Position Sensor
  • Jack Stands
  • Vehicle Jack
  • Mechanic Toolset Metric

Procedure

  1. Park your Mazda on level ground. Engage parking brakes. Let the engine cool down.
  2. Jack up the front right (passenger) side wheel. The CPS sensor is located on the same side that you have the serpentine belt. It is not on the transmission side.
  3. Remove the front wheel. Secure your vehicle with a good set of jack stands and block a tire as well, so your car doesn't roll.
  4. Remove the plastic wheel well liner. It is held in place with several plastic clips, 8mm or 10 mm nut depending on the Mazda model.
  5. Locate the crankshaft position sensor.
  6. Unplug the electrical connector.
  7. Remove two 8mm bolts.
  8. Before removing the old crankshaft position sensor, mark the old sensor's exact position with a marker. You need to install the new CPS sensor in the same location.
  9. Install a new crankshaft position sensor on your Mazda engine block. Notice that the mounting holes are not round but oval. This allows the sensor to be moved slightly.
  10. Before you tighten the screws, make sure that the new sensor is in the same location as the old one.

Notes

If the crank sensor fails on your Mazda, your car will refuse to start or will start intermittently.

Related Problems

Fuel Pump

  • If your Mazda is not starting, it is possible that the fuel pump has failed or is not generating enough pressure.

Ignition System

  • Spark plugs and ignition coils can also be effective and could be another reason why your Mazda does not start.

Crankshaft sensor location on 2003 6 (V6)

Can someone please point me in the right direction as to where the crankshaft position sensor is located (pics?) on a 2003 Mazda 6 with a V6 and a manual tranny. Any advice on the best way to access would be helpful too. I know what it looks like I just can't seem to find it. Thanks
