Crankshaft Position Sensor: Testing and Inspection

Component locations, refer to "Component Overview - I " Locations

- All sensors correctly installed, securely connected
- Disconnect (black) harness connector.







- Switch Fluke 83 multimeter to resistance range and connect between CKP sensor connector terminals 1 and 2 (in connector bracket) using jumper wires from VW 1594 test kit.
Specified value: approx. 1000 ohm

If the specified value is not obtained:
- Replace Crankshaft Position (CKP) sensor.

If the specified value is obtained:
- Connect multimeter between terminal 1 and 3 (GND), then between terminals 2 and 3 (GND).
Specified value: Infinite ohm (open)

If the specified value is not obtained:
- Replace Crankshaft Position (CKP) sensor.

If the specified value is obtained:
- Check wiring for continuity or short between CKP sensor and ECM using wiring diagram.
- Connect VAG 1598/19 test box to ECM harness connector.







- Check CKP sensor shielding for continuity by connecting multimeter between terminal 3 and engine Ground (GND).
Specified value: max. 1 ohm
- Check wiring for continuity between CKP sensor connector terminal 1 and test box socket A9, then between CKP sensor connector terminal 2 and test box socket A10.
Specified value: max. 1 ohm

If the specified values are not obtained:







- Eliminate short or open circuit in wiring.

CKP sensor ECM connector A or
terminal number engine ground (GND)
1 A8
2 A10
3 Engine Ground (GND)

If wiring is OK:
- Replace ECM.
