Inspection/Repair - Component Inspection

Component Inspection

1. IG "OFF".
2. Disconnect Fuel Level Sensor harness connector.
3. Measure the resistance between terminal 1 and 3 of Fuel Level Sensor harness connector.
(Component side) (Measure the resistance while changing the float position.)
A. Specification :






CAUTION:
S/F : Sensor Full
G/F : Gauge Full
W/G : Warning Point
G/E : Gauge End
S/E : Sensor End
7/8,6/8,5/8,4/8,3/8,2/8,1/8 : Indicator position in cluster




4. Is the measured resistance within specification?
YES
1) Substitute with a known-good ECM and check for proper operation.
If the problem is corrected, replace ECM and then go to "Verification of Vehicle Repair" procedure.

CAUTION:
There is a memory reset function on scantool that can erase optional parts automatically detected and memorized by PCM.
Before or after testing PCM on the vehicle, use this function to reuse the PCM on the others

NO
1) Substitute with a known-good Fuel Level Sensor and check for proper operation.
If the problem is corrected, replace Fuel Level Sensor and then go to "Verification of Vehicle Repair" procedure.
