Ok guys first things first, about a month ago I took my car (01 a4 c5) in because the Service active handling light would come on after driving 5-10 miles, the car would swerve slightly and the cars active handling would turn its self off and give the service message and then it would drive ok, yet without active handling, I take the car in and they say its a right rear wheel speed sensor. 795$ part btw and thats the code it was throwing. Anyway I get the car back suposedly fixed, the next day I drive the car BOOM FUGIN light right back in my face yet now the car slightly brakes before it starts to swerve and turn the active handling system off.(maybe it slightly braked before, i dont remeber) So i take it to the dealer. Now they say its a Steering positioning sensor. The light is still on yet I cant pull any codes with my obd2 scanner to confirm this, and tried two other scanners to see if mine was bad. How do they know this is really the problem? are they bsing me or doing some trial and eror crap, has anyone had this steering pos sen go out? and whats the code for this steering pos


ME = HERE TAKE SOME MORE MONEY. = dealer

You can get the codes from the DIC.

I think you need a techII to read the steering wheel sensor.

$795 for a wheel sensor? Wow!

 

I think it's integrated into hub...if I'm not mistaken.

 

pull the codes off the dic press options and hold then fuel 4 times and it should activate diagnosis mode this should ge u all the codes.

 

Steering position sensor can be fixed with simple volt meter. Separate the sensor wiring harness at the firewall (inside the car), raise the front on jack stands. Measure the voltage on the middle (light blue) input....it usually reads .24V or 4.8V. Turn steering wheel until it reads 2.5V, unlosen steering wheel, center, and tighten steering. Reattach wiring harness and you done.

 

Ok scaned the thing with its self dic following codes,
tcs c1276h c1287h c1288h I see that one of those is improper rate for the sps but the others umn whats up

more found that they didnt tell me about? what are they
u1016h
u1064h
u1040h
u1088h
u1176h

1276 is a delivered torque signal the pcm sends to the electronic brake and traction control module (EBTCM). There are several reasons why this may not be received including dirty contacts, etc. The normal electronic debug type of things.

1287 is a steering sensor rate malfunction. The EBTCM senses a steer rate (how fast the steering wheel is being turned) that exceeds the limits set by the EBTCM. There are 4 signals involved. Phase A, Phase B, Analog voltage and the index pulse. Again dirty contacts and loose connections can cause a problem. Phase A and Phase B are used by the EBTCM to tell which direction the driver is trying to steer during an ABS event and are also used to determine the rate. The rate value is used to control the amount of boost from the Magnasteer steering rack.

A diagnostic the tech can do with the tech 2 is monitor the Phase A and Phase B signals while turning the steering wheel. If they do not change uniformly the diagnostic procedure says to replace the steering wheel position sensor. Other branches in the diagnostic procedure lead to EBTCM replacement.

1288 steering sensor circuit malfunction. This code is set when the analog voltage mentioned above falls out of the .2 to 4.8 V range. It can indicate an open or short of the signal. Procedures lead to open circuits or in some cases replacement of the EBTCM.

All 3 are history codes so the car should have been working fine when you took the codes.

You should get a Service Manual so you can understand what is happening when these codes are set. Just reading the code doesn't provide enough info to make a repair.

The wheel speed sensor is part of the wheel bearing and you can get cheaper ones from the aftermarket. The steering wheel sensor failure usually shows up as a Service Vehicle Soon message. The U codes aren't particularly meaningful. They represent State of Health messages the various modules send each other on a regular basis. Like any networked system sometimes a message is missed but is OK on the next try. The results are those codes and the fact that they are all history codes indicates things are alright now.

thanks for the help going to try adjusting the steering pos sen, if that doesnt work ill replace it, its only 68 bucks. thanks guys
