P2175-LOW AIRFLOW/RESTRICTION DETECTED (SLOW ACCUMULATION) (CONTINUED) 14. RESISTANCE IN THE (K1) MAP SIGNAL CIRCUIT Turn the ignition off. Disconnect the C2 PCM harness connector. Measure the resistance of the (K1) MAP Signal circuit from the MAP Is the resistance below 5.0 ohms? Yes >> Go To 15 No >> Repair the excessive resistance in the (K1) MAP Signal circuit Perform the POWERTRAIN VERIFICATION TEST. (Refer 15. (K1) MAP SIGNAL CIRCUIT SHORTED TO GROUND Measure the resistance between ground and the (K1) MAP Signal cir- Is the resistance above 100k ohms? Yes >> Go To 16 No >> Repair the short to ground in the (K1) MAP Signal circuit. Perform the POWERTRAIN VERIFICATION TEST. (Refer 9 - 1004 ENGINE ELECTRICAL DIAGNOSTICS WK |
