Resistance Inspection

WARNING: This page is about a different car, the 2005 Mazda 6. However, it is still accessible from the selected car via links, so may be relevant.

Disconnect the CKP sensor connector.
Measure the resistance between CKP sensor terminals A and B using an ohmmeter.
- If not as specified, replace the CKP sensor.
- If CKP sensor resistance is normal, but RPM PID value is out of specification, perform the "Circuit Open/Short Inspection".
  Specification
  
  400-550 ohms
