brake pedal is pressed or has failed. Acceleration rate and Engine output are limited. One trip fault and the code will set within 5 seconds . ETC light is flashing. POSSIBLE CAUSES (F855) 5-volt supply circuit open (F855) 5-volt supply circuit shorted to ground (K23) APP sensor no.1 signal circuit open (K23) APP sensor no.1 signal circuit shorted to ground (K23) APP sensor no.1 signal circuit shorted to the (K167) APP sensor no.1 return circuit (K23) APP sensor no.1 signal circuit shorted to the (K400) APP sensor no.2 return circuit APP sensor PCM Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. DIAGNOSTIC TEST 1. APP SENSOR BELOW 0.25 OF A VOLT Ignition on, engine not running. With a scan tool, read the APP Sensor No.1 voltage. Q: Is the voltage below 0.25 of a volt? YES: Go To 2 NO: Go To 11 2. (F855) 5-VOLT SUPPLY CIRCUIT WHEN MONITORED: With the ignition on and no other APPS No.1 DTCs present. SET CONDITION: When the APP Sensor No.1 voltage is too low. Engine will additionally idle if the Turn the ignition off. Disconnect the APP Sensor harness connector. Ignition on, engine not running. Measure the voltage on the (F855) 5-volt Supply circuit in the APP Sensor harness connector. Q: Is the voltage between 4.5 and 5.2 volts? YES: Go To 3 NO: Go To 8 3.

NOTE: The compressor clutch assembly can be serviced with the refrigerant system fully-charged. Typical A/C compressor shown in illustrations. 1. Disconnect and isolate the negative battery cable. 2. Remove the accessory drive belt. 3. Disconnect the engine wire harness from the compressor clutch field coil connector (1) located on the top of the A/C compressor (5). 4. Remove the bolts that secure the A/C compressor to the engine and support the A/C compressor. 5. Carefully remove the compressor clutch field coil connector and wire lead from the connector bracket (2). 6. Remove the compressor shaft bolt (3). A band-type oil filter wrench or a strap wrench may be used to hold the clutch plate (4) from rotating during bolt removal. CAUTION: Do not pry between the clutch plate and the pulley and bearing assembly to remove the clutch plate from the compressor shaft as this may damage the clutch plate. NOTE: Use care not to lose any clutch shim(s) during removal of the clutch plate, as they may be reused during the clutch plate installation process. 7. Tap the clutch plate (2) lightly with a plastic mallet to release it from the splines on the compressor shaft (1) and remove the clutch plate and shim(s) (3). 8. Using snap ring pliers (2), remove the snap ring (1) that secures the pulley and bearing assembly (3) to the front of the A/C compressor and remove the pulley and bearing assembly. 9. Using snap ring pliers (Special Tool C-4574 or equivalent) (1), remove the snap ring (4) that secures the compressor clutch field coil (2) to the front of the A/C compressor (3) and remove the field coil. INSTALLATION NOTE: Typical A/C compressor shown in illustrations.
