TSB – Long Crank Time Due To Possible Contact Of Camshaft Sensor To Camshaft Gear

NUMBER: 08-023-07
GROUP: Electrical
DATE: October 06, 2007

SUBJECT:
Long Crank Time Due To Possible Contact Of Camshaft Sensor To Camshaft Gear

OVERVIEW:
This bulletin involves the replacement of the engine camshaft sensor.

MODELS:
2007 (JK) Wrangler

SYMPTOM/CONDITION:
The customer may experience one of the following conditions:

a). Long engine crank time.
b). Two engine start attempts prior to engine starting.
c). Due to the “TIP Start Feature? on automatic transmission equipped vehicles, once the ignition key / switch has been released from the “START? position, the starter may stay engaged for up to 10 seconds while the engine attempts to start.

The above conditions may be due to the position of the camshaft sensor to the camshaft gear. The sensor spacer gasket may have come loose during engine assembly and caused the camshaft sensor to be adjusted too close or in contact with the camshaft gear.

  1. Wow, I thought I had something seriously going wrong with my JK! I have a manual, and every few mornings it takes a long time to start, I was getting scared! Thanks for the heads up!

  2. I have had this problem happen several times, if the engine did not start I would turn the igniton on and off several times and it started right up.
    I thought it was a fuel injector problem.
