RL V6-3.5L (2007)
58. Check for continuity between PCM connector terminal C6 and body ground.
Is there continuity?
YES - Repair short in the wire between the PCM (C6) and the MAP sensor or the output shaft (countershaft) speed sensor.
NO - Update the PCM if it does not have the latest software, or substitute a known good PCM, then recheck. If the symptom/indication goes away
with a known good PCM, replace the original PCM.
59. Measure voltage between body ground and PCM connector terminal C14.
Is there about 5 V?
YES - Go to step 67.
NO - Go to step 60.
60. Turn the ignition switch OFF.
61. Disconnect the connector from each of the following sensors, one at a time, while measuring voltage between body ground and PCM connector
terminal C14 with the ignition switch ON (II).
-
Intake manifold tuning (IMT) actuator
-
Exhaust gas recirculation (EGR) valve
-
Input shaft (mainshaft) speed sensor
Is there about 5 V?
YES - Replace the part that restored 5 V when disconnected.
