Acura RL. Manual - part 715

67. Continue to check for continuity between PCM connector terminal C6 and body ground, while

disconnecting these parts, one at a time:



MAP sensor 3P connector



Output shaft (countershaft) speed sensor 3P connector

Does continuity go away when one of the above components is disconnected?

YES - Replace the part that caused an open when it was disconnected

NO - Repair short in the wire between the PCM (C6) and the MAP sensor, the output shaft
(countershaft) speed sensor

68. Check for continuity between PCM connector terminal C14 and body ground.

Is there continuity?

YES - Go to step 69.

NO - Go to step 70.

69. Continue to check for continuity between PCM connector terminal C14 and body ground, while

disconnecting these parts, one at a time:



EGR valve 6P connector



Input shaft (mainshaft) speed sensor 3P connector



IMT actuator 5P connector

Does continuity go away when one of the above components is disconnected ?

YES - Replace the part that caused an open when it was disconnected

NO - Repair short in the wire between the PCM (C14) and the EGR valve, the input shaft (mainshaft)
speed sensor, or the IMT actuator

70. Check for continuity between PCM connector terminal D2 and body ground.

substitute a known-good PCM (see SUBSTITUTING THE PCM ), then recheck. If the
symptom/indication goes away with a known-good PCM, replace the original PCM (see PCM
REPLACEMENT )

73. Continue to check for continuity between PCM connector terminal E12 and body ground, while

disconnecting these connectors one at a time.



APP sensor 6P connector



FTP sensor 3P connector

Does continuity go away when one of the above components is disconnected?

YES - Replace the part that caused an open when it was disconnected

NO - Repair short in the wire between the PCM (E12) and the APP sensor B or the FTP sensor

INJECTOR REPLACEMENT

1. Relieve the fuel pressure (see FUEL PRESSURE RELIEVING ).

2. Remove the intake manifold (see REMOVAL ).

3. Disconnect the connectors from the injectors (A).
