E065

Code E065:

Cruise Control Circuit:

DESCRIPTION:

Code E065 will detect a cruise control servo position sensor shorted to ground. The cruise position sensor is a variable inductance sensor whose inductance changes with servo position. Code E065 sets when the PCM/ECM detects a low voltage indicating a short to ground in the cruise servo position sensor circuit.

TEST CONDITIONS:

1. Tested continuously.

FAILURE CONDITIONS:

1. Servo position 6.3% or less for 1 second.

ACTION TAKEN:

1. Disable cruise control.
2. Code set, No Service lamp.

NOTES ON FAULT TREE:

1. PCM/ECM data value ED70 displays servo position. The range is approximately 4% to 94%. If the servo will not go to full stroke, the vacuum supply, servo, or vacuum brake release circuit is leaking.

2. Check dash to engine connector as possible source of intermittent in signal line.
