Troubleshooting

Step
1 1) Turn the ignition switch "OFF".
2) Check the MAP sensor connector for loose or poor
contacts.
If OK, then check the MAP sensor lead wire continuity.
3) Disconnect the MAP sensor connector at sensor.
4) Check the continuity between "R" wire terminal and "B/
W" wire terminal.
Is it no continuity?
2 1) With the ignition switch "ON", check the voltage at the
"R" wire terminal of MAP sensor and ground.
Is the voltage approx. 4 – 5 V?
3 1) With the ignition switch "OFF", disconnect ECM
connectors from ECM.
2) Check the continuity between "R" terminal of MAP
sensor connector and No. 33 terminal of ECM
