This Week’s Winners

On this edition of Fix of The Week: sensors out of spec in a Nissan, a sticky window in a Honda, and another with a finicky immobilizer.

 

2006 Nissan Titan – Sacto Auto Repair

This customer had replaced both the camshaft and crankshaft sensor using aftermarket parts. They reset the check engine but it would turn back on after 1 drive cycle. The RPM fluttered and there was extended cranking. We tested the resistance of both sensors—those were within spec. We also checked the voltage to the sensors and suspected the problem was with the cam and crank sensor being out of spec once the vehicle was within normal operating temperature. We replaced with OEM HITACHI sensors. We drove the vehicle twice to verify the concern was corrected and the RPM gauge no longer flutters and check engine light stayed off.  

 

2004 Honda Pilot – Plymouth Village Automotive

The customer came in because her vehicle’s right rear window was stuck down. When trying to command the window up with the master switch, the door locks would activate. The intermittent battery light and warning lights in the dash came on while driving. We removed the passenger multiplex module at the right kick panel to check powers and grounds. The module was wet with water. The customer stated she got a car wash before the problem started and a new windshield was installed 3 months prior, which was leaking. We dried out the module and the window works properly again.

 

2006 Pontiac G6 – TGK Automotive

We performed an oil change on this Honda and cleared the P0420 code for the customer at their request. The vehicle would not start, and the immobilizer green key light would not light up—ever. There was no spark and no injector pulse. The starter worked fine and all communication was fine except the immobilizer, which both scan tools said was not equipped on this vehicle. That had us scratching our heads.  

There were no codes in any module and the launch torque and Snap-On Modis ultra were both fully updated. We tore the steering column clamshell cover off and tested for powers and grounds at the immobilizer plugs, all of which tested good. With the key on, we unplugged both connectors for 10 seconds. Upon plugging back in, the immobilizer light came on and flashed a few times then went out. The car starts fine now, and we’re guessing the immobilizer needed to be reset from clearing codes.
