6E2–110 6VD1 3.2L ENGINE DRIVEABILITY AND EMISSIONS DTC P0108 – MAP Sensor Circuit High Voltage
Step Action Value(s) Yes No 1 Was the “On-Board Diagnostic (OBD) System Check” — Go to Step 2 Go to OBD System Check 2 1. If the engine idle is rough, unstable or incorrect, repair the idle problem before using this chart. Refer Symptoms section. 2. With the engine idling, note the MAP value on the Tech 2. Is the MAP reading above the specified value? 90 kPa Go to Step 4 Go to Step 3 3 1. Ignition “ON,” engine “OFF.” conditions as noted. 4. Using a Tech 2, monitor “DTC” info for DTC P0108. Does the Tech 2 indicate DTC P0108 failed this — Go to Step 4 Refer to Diagnostic Aids 4 1. Ignition “OFF.” 2. Is the MAP sensor voltage at the specified value? (If no, 0.0 V 11 kPa Go to Step 5 Go to Step 6 5 Probe the sensor ground circuit with a test light to B+. Is the test light “ON?” — Go to Step 7 Go to Step 9 6 1. Check the MAP signal circuit for a short to voltage or a short to the 5 volt reference “A” circuit. 2. If the MAP sensor signal circuit is shorted, repair circuit as necessary. Was the MAP sensor signal circuit shorted? — Verify repair Go to Step 11 7 1. Check for a poor sensor ground terminal connection at the MAP sensor electrical connector. 2. If a problem if found, replace the faulty terminal. Did the terminal require replacement? — Verify repair Go to Step 8 8 Check for a plugged or leaking vacuum supply to the Is the vacuum supply plugged or leaking? — Verify repair Go to Step 12 9 1. Check for a poor sensor ground terminal connection at the PCM. 2. If a problem is found, replace the faulty terminal. Did the terminal require replacement? — Verify repair Go to Step 10 10 1. Check the continuity of the MAP sensor ground circuit. 2. If the MAP sensor ground circuit measures over 5 ohms, repair open or poor connection. Was a condition found and corrected? — Verify repair Go to Step 11 |
