Checking Resistance
- Disconnect Crankshaft Position (CKP) sensor connector (located on left side of cylinder block). Using a DVOM, measure resistance between CKP sensor connector (sensor side) terminals No. 1 and 2. See Fig 1 .
- Resistance should be approximately 1000 ohms. If resistance is not to specification, replace CKP sensor. If resistance is to specification, go to next step.
- Connect DVOM between CKP sensor connector (sensor side) terminals No. 1 and 3, then terminals No. 2 and 3. Resistance should be infinite (open). If resistance readings are not infinite, replace CKP sensor.
