Hyundai Tech Tip: No Spark, No Injector Pulse on 2002 Sonata 2.4 L Models

You may get a customer complaint that the vehicle died while in Drive, then wouldn't start. There is no spark and no injector pulse, and no engine rpm on the scanner while cranking, and it's setting a Crankshaft Position (CKP) sensor code P0335.

Tests/Procedures:

1. Verify the battery voltage to the CKP sensor on the pink wire.

2. Verify that the ground for the CKP sensor is good on the black wire — look for 0.05 volts or less.

3. Scope the CKP sensor on the yellow wire for a consistent 0-5 volt square wave signal.

4. Check for a possible timing belt shredding, affecting the CKP sensor.
