3. When the voltage is abnormal, check the sensor power and ground circuits.
HARNESS TEST:
1. Disconnect the Crankshaft Position/Camshaft (TDC) sensor connector and turn the key to the ON position.
2. Using a voltmeter, measure the power supply voltage between the harness connector terminal 1 and ground.
Voltage:
System voltage.
3. Check for continuity between the Crankshaft Position/TDC sensor harness connector terminal 4 and ground.
Continuity:
Should exist.
4. Using a voltmeter, measure the output circuit voltage between the harness connector terminal 1 and ground.
Voltage:
4.8 - 5.5 Volts.
If any of the previous tests produce unsatisfactory results, the harness will need to be repaired or replaced. Once repairs have been completed, clear
the trouble codes and road test the vehicle to confirm that the repair has corrected the problem and the code doesn't return.
If the same trouble code reoccurs, it is possible that there is an intermittent failure of the component or the ECM. Check for looseness at all harness
junctions and test for an intermittent failure.
