DRIVEABILITY - GAS
P0107-MAP SENSOR VOLTAGE TOO LOW —
TEST
3 With the DRBIII , monitor the MAP Sensor voltage with the Sensor still discon-
nected.
Is the voltage above 1.2 volts?
Yes → Replace the MAP Sensor.
→ Go To 4
No
4 Turn the ignition off.
Disconnect the PCM harness connectors.
Measure the resistance between ground and the (K1) MAP Sensor Signal circuit at
the MAP Sensor harness connector.
Is the resistance below 100 ohms?
Yes → Repair the short to ground in the ( K1) MAP Sensor Signal circuit.
→ Go To 5
No
5 Measure the resistance between the (K1) MAP Sensor Signal circuit and the (K900)
Sensor ground circuit at the MAP Sensor harness connector.
Is the resistance below 100 ohms?
Yes → Repair the short between the (K900) Sensor ground circuit and
→ Go To 8
No
6 Turn the ignition off.
Disconnect the PCM harness connectors.
Measure the resistance in the (K7) 5-volt Supply circuit from the MAP Sensor
harness connector to the PCM harness connector.
Is the resistance below 100 ohms?
Yes → Go To 7
→ Repair the open in the (K7) 5-volt Supply circuit.
No
7 Measure the resistance between ground and the (K7) 5-volt Supply circuit at the
MAP Sensor harness connector.
Is the resistance below 100 ohms?
Yes → Repair the short to ground in the (K7) 5-volt Supply circuit.
→ Go To 8
No
8 NOTE: Before continuing, check the PCM harness connector terminals for
corrosion, damage, or terminal push out. Repair as necessary.
Using the schematics as a guide, inspect the wire harness and connectors. Pay
particular attention to all Power and Ground circuits.
If there are no possible causes remaining, view repair.
