4
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 between the MAP Sensor
harness connector and the PCM harness connector.
Is the resistance below 5.0 ohms?
All
Yes
→ Go To 5
No
→ Repair the open in the (K6) 5-volt Supply circuit.
Perform POWERTRAIN VERIFICATION TEST VER - 5 - 1.6L.
5
Turn the ignition off.
Disconnect the MAP Sensor harness connector.
Turn the ignition on.
With the DRBIII
t, monitor the MAP Sensor voltage.
Is the voltage above .04 volts?
All
Yes
→ Replace the MAP Sensor.
Perform POWERTRAIN VERIFICATION TEST VER - 5 - 1.6L.
No
→ Go To 6
6
Turn the ignition off.
Disconnect the MAP Sensor harness connector.
Disconnect the PCM harness connector.
Measure the resistance of the (K1) MAP Sensor Signal circuit between the MAP
Sensor harness connector and ground.
Is the resistance below 5.0 ohms?
All
Yes
→ Repair the short to ground in the (K1) MAP Sensor Signal circuit.
Perform POWERTRAIN VERIFICATION TEST VER - 5 - 1.6L.
No
→ Go To 7
7
Turn the ignition off.
Disconnect the MAP Sensor harness connector.
Disconnect the PCM harness connector.
Measure the resistance between the (K1) MAP Sensor Signal circuit and the (K901)
Sensor ground circuit in the MAP Sensor harness connector.
Is the resistance below 100 ohms?
All
Yes
→ Repair the short between (K901) Sensor ground circuit and the
(K1) MAP Sensor Signal circuit.
Perform POWERTRAIN VERIFICATION TEST VER - 5 - 1.6L.
No
→ Go To 8

NOTE: Before Continuing: Disconnect the PCM harness connector and
check the related wiring 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.
