Disconnect the MAPS and PCM connectors and inspect for looseness, poor connection, bending, corrosion, contamination, deterioration or damage. Reconnect the connectors.

Connect the GDS and go to "Current Data".

Monitor MAPS values in Current Data, check and wiggle the harness(es), connector(s), and terminal(s).

Any change in the values indicates a poor connection. Was a connector problem found?

	▶ Repair the connector. Go to "Verification of Vehicle Repair" procedure.
	▶ Go to "Power Circuit Inspection" procedure.

IG "OFF". Disconnect MAPS connector.

IG "ON".

Measure the voltage between power terminal of MAPS harness connector and ground.

Is the measured voltage within specification ?

	▶ Go to "Signal Circuit Inspection" Procedure.
	▶ Repair open or short in harness. Go to "Verification of Vehicle Repair" procedure.

IG "OFF".

Disconnect MAPS and PCM connector.

Measure the resistance between signal terminal of MAPS harness connector and ground.

Is the measured resistance within specification ?

	▶ Go to "Check open in harness" as follows.
	▶ Repair short to ground in harness. Go to "Verification of Vehicle Repair" procedure.

IG "OFF". Disconnect MAPS and PCM connector.

Measure resistance between signal terminal of MAPS harness connector and MAPS signal terminal of PCM harness connector.

Is the measured resistance within specification ?

	▶ Go to "Ground Inspection" procedure.
	▶ Repair open in harness. Go to "Verification of Vehicle Repair" procedure.

IG "OFF". Disconnect MAPS connector turn IG "ON".

Measure voltage between signal terminal of MAPS harness connector and chassis ground (Measurement "A")

Measure voltage between signal and ground terminals of MAPS harness connector (Measurement "B")

Is the measured voltage within specification ?

	▶ Go to "Component Circuit Inspection" procedure.
	▶ Repair contact resistance or open in harnesss. Go to "Verification of Vehicle Repair" procedure.
