Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Code 82, 3X Signal Error: Notes
Magnetic crank sensor is used to determine engine crankshaft position much the same way as the pick-up coil did in distributor type systems. Sensor is mounted in block near a 7-slot wheel on crankshaft. Rotation of wheel creates a magnetic field in sensor which induces a voltage signal. Electronic ignition module then processes this signal and creates reference pulses needed by PCM to trigger correct coil at correct time.
- This test will determine if 12-volt supply and a good ground are available at ignition module.
- Checks for resistance of crank sensor and connections.
- Voltage will vary in this test depending on cranking speed of engine.
