Component Inspection
1. Ignition "ON" & Engine "ON".
2. Turn the steering wheel to the left or right.
3. Measure signal waveform between terminal "1, 4, 5" of the steering wheel angle sensor harness connector and chassis ground.
A. Specification : High : 2.7-4.4V, Low : 1.1-2.3V
4. Is the measured signal waveform within specifications ?
YES
1) Fault is intermittent caused by poor connection in steering sensor harness and/or HECU's connector or was repaired and HECU memory was not cleared. Go to "Verification of Vehicle Repair" procedure.
NO
1) Substitute with a known-good steering wheel angle sensor and check for proper operation. If problem is corrected, replace steering wheel angle sensor and then go to "Verification of Vehicle Repair" procedure.
