▶ Go to "Terminal and Connector inspection" procedure.
▶ Fault is intermittent caused by poor contact in the sensor's and/or ECM's connector or was
repaired and ECM memory was not cleared. Thoroughly check connectors for looseness, poor
connection, ending, corrosion, contamination, deterioration, or damage. Repair or replace as
necessary and go to "Verification of Vehicle Repair" procedure.
Terminal and Connector Inspection
1. Many malfunctions in the electrical system are caused by poor harness and terminals. Faults can also be caused by
interference from other electrical systems, and mechanical or chemical damage.
2. Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or
damage.
3. Has a problem been found?
▶ Repair as necessary and go to "Verification of Vehicle Repair" procedure .
▶ Go to " Signal Circuit Inspection " procedure.
Signal Circuit Inspection
■ Check voltage
1. IG "OFF" and disconnect CKPS connector.
2. IG "ON".
3. Measure voltage between low signal terminal of CKPS harness connector and chassis ground.
4. Measure voltage between high signal terminal of CKPS harness connector and chassis ground.
Specification : Approx. 2.4V
5. Is the measured voltage within specification ?
▶ Go to "Component Inspection" procedure.
▶ Go to "Check short in harness" as follows.
■ Check short in harness
1. IG "OFF" and disconnect CKPS connector and ECM connector.
2. Measure resistance between low(high) signal terminal of CKPS harness connector and chassis
ground.(Measurement "A")
3. Measure resistance between low signal and high signal terminals of CKPS harness connector.(Measurement "B")
Specification : Infinite
4. Is the measured resistance within specification?
▶ Go to "Component Inspection" procedure.
▶ Repair short in harness, and go to "Verification of Vehicle Repair" procedure.
