I'm gonna revive this one, as I'm working on a friend's car, and it just threw a 00281 code for the speed sensor. She was in for something completely different, but electronic as well. It's not a TDI, and I'm auto-trans retarded
2002 Jetta 1.8T Engine AWP: 137,000 miles
9A 5-speed tiptronic transmissionSo, this is a friend's car. I should first note that it had a bunch of electrical problems like:
1) Door locks would lock and unlock while driving
2) Car would turn itself off
3) Radio would turn itself off
4) VAG-COM would intermittently disconnect while plugged in.
I swapped out the ignition switch, the 101 relay, and the auto trans park relay. I drove it for a few days. No problems whatsoever.
I did notice a mouse had been living in the rain-tray area, but I inspected all the wires from there to the battery tray, and saw no chewed wires anywhere.
Anyway, after doing all the electrical work, I then did the timing belt on it, as it was waaay past due. Again, the car ran great with no problems (codes), but there were notable rough shifts from 1st to second when cold. It got better when warm, so I just figured dirty fluid.
She comes to pick up the car. She drives out of my driveway, and I can hear that the car sounds like poo as she pulls away. She calls 4 minutes later saying that the car is not running right, it's shifting REAALLLY hard and the CEL is on.
Here is the code I pulled up:
Saturday,11,July,2009,23:18:46:39225
VCDS Version: Release 805.3
Address 02: Auto Trans
Control Module Part Number: 09A 927 750 T
Component and/or Version: AG5 Getriebe 09A 0162
Software Coding:
Work Shop Code:
1 Fault Found:
00281 - Vehicle Speed Sensor (G68)
03-10 - No Signal - Intermittent
That the G68 is showing fault is worrying me (car has 137k on it), as does the fact that there is no trans coding or workshop code. I don't know k-rap about about auto transmissions.
How does one check the resistance on the sensor? I only have a Bentley, and I can't seem to find info on testing the sensors in it.
Thanks
