AA26 - Check VPWR Continuity

- Key "OFF".

- Disconnect Powertrain Control Module (PCM). Inspect for damaged or pushed out pins, corrosion, loose wires, etc. Service as necessary.

- Install breakout box, leave PCM disconnected.

- Camshaft Position (CMP) sensor disconnected.

- Measure resistance between VPWR circuit at CMP sensor vehicle harness connector and test pin 37 or 57 at the breakout box.

- Is resistance less than 5.0 ohms?

Yes -- Go to pinpoint test step B1. B1 - Check Battery Voltage

No -- Service open circuit. Remove breakout box. Reconnect all components. Rerun quick test. Quick Test Appendix (Detailed Testing Instructions)
