TEST
3
Turn the ignition off.
Disconnect the MAP Sensor harness connector.
Ignition on, engine not running.
With the DRBIII , monitor the MAP Sensor voltage.
Is the voltage above 1.2 volts?
Yes → Replace the MAP Sensor.
→ Go To 4
No
4
Turn the ignition off.
Disconnect the MAP Sensor harness connector.
Disconnect the PCM harness connector.
Measure the resistance between ground and the (K1) MAP Signal circuit at the MAP
Sensor harness connector.
Is the resistance below 100 ohms?
Yes → Repair the short to ground in the (K1) MAP Signal circuit.
→ Go To 5
No
5
Turn the ignition off.
Disconnect the MAP Sensor harness connector.
Disconnect the PCM harness connector.
Measure the resistance between the (K1) MAP Signal circuit and the (K4) Sensor
ground circuit in the MAP Sensor harness connector.
Is the resistance below 100 ohms?
Yes → Repair the (K4) Sensor ground shorted to the (K1) MAP Signal
→ Go To 6
No

NOTE: Before continuing, check the PCM harness connector terminals for
corrosion, damage, or terminal push out. Repair as necessary.
If there are no possible causes remaining, view repair.

7
Turn the ignition off.
Disconnect the MAP Sensor harness connector.
Disconnect the PCM harness connector.
Measure the resistance of the (K6) 5 Volt Supply circuit in the MAP Sensor harness
connector to ground.
Is the resistance below 100 ohms?
Yes → Repair the short to ground in the (K6) 5 Volt Supply circuit.
→ Go To 8
No
