This Week’s Winners
On this edition of Fix of The Week: A Kia Sedona with a sticky key, a Nissan that won’t cooperate on the freeway, and a hesitant Honda.
2006 Kia Sedona – Jim’s Auto Repair Svc
A Customer was concerned that their battery was being drained overnight because their ignition key would not come out as the key would not turn to lock position. We found that if the negative cable was removed from the battery that the key would then turn off and come out of the ignition. This happened because the shifter knob makes contact with a small slanted white plastic piece that screws onto the shifter.
We figured that the shifter knob must wear down after extended use so all we had to do was to remove the shifter knob (Put the shifter in low gear position and remove two Phillips screws) and then we screwed the small white plastic piece down further. Key was then able to go to the lock position and come out.
2011 Nissan Sentra – Fearnside’s Fix-All
A customer with a 2011 Nissan Sentra would be driving their car at highway speeds and suddenly they would lose cruise control, the car would not accelerate, and the traction control light would turn on.
We Scanned ABS module for codes and found C1116 for brake light circuit but we could not duplicate the problem. So we suggested the customer replace the brake light switch and re-test. The customer reported the car did the same thing after driving for a while. Next, we checked the brake light wiring and brake light bulb and found that the LED strip for third brake light was not working. There were broken wires in harness between car and trunk lid, these wires were shorting out and causing the problem. Once we ran new wires and the problem was fixed.
2000 Honda Accord – Borough of Chatham
This Honda came in with code P1381 and intermittent hesitation while driving. The code is for cylinder position sensor interruption. The sensor is part of the distributor.
We removed the distributor cap to check the (CYP) sensor to see if the sensor is damaged or if it is missing Rf shield. Shield helps keep the noise from distorting the signal. Next we hooked up the scope to CYP signal wire Yellow, and ground Black coming out of distributor and checked for distortion on the analog signal going to the PCM. We also unplugged the alternator while watching the signal. The Signal cleared up after unplugging the alternator so it turned out that a bad diode in the alternator caused the CYP sensor signal to distort and throw the error code. We replaced the alternator and everything was back to normal.
