As With The Last Thread, My First Problem Happened This Morning When I Started My Car To Come To Work. The Esp/bas Light Was On Along With The Esp Off Light(the Car With The Wavy Street Marks). They Were On For About 30 Seconds After I Started Driving And Then Went Off. Any Ideas? The Car Only Has 560 Miles On It.

Here in Canada I recieved a TSB for reprogramming for the ABS system.

I had the same problem.(510 miles) My ESP and ESP/BAS light came on yesterday and stayed on. When I went to work this morning they went off. I believe it detected a problem and self corrected itself. It has me a little worried. I have had many Jeeps with no problems. I guess its a small price to pay for having one of the coolest SUV's on the market. I am keeping a very close eye on my Nitro. I hope to have no furthur problems!

yeah exactly nitro57. i have gone 300 more miles now and am yet to have a repeat event. it worried me also the morning that happened. i am going to bring it to dealer attention when it goes in next week for first 1k oil change.

same thing

I noticed it the second day and third day i had my vehicle. The first time happened around 45 miles and then again this morning when I started the car with about 95 miles...... keep your eyes and ears peeled and let us know if anyone has anything done about it...

Happened to me today as well. I called the dealer and they have an appointment setup for me first thing tomorrow morning

I've had my Nitro for 2 days, today the Esp light came on and stayed on. Then the Engine light came on. Took it back to the dealer and they replaced a brake switch that they said was shorting.

Well mine just came back from the shop today for the same problem. This was what they wrote on the work order (stored code C121A 92 Key cycles ago and 5K miles steering angle sensor not initialized. Has initialized itself since.) Don't know if that makes any sense to anyone.

Ok, i've had this problem, and the dealer replaced clkspring, worked good for a month the the other day it came back on and stayed on, after 3 key cycles on and off, the light went out, so on 4/27 back to the shop, and discuss problem, last time the service adviser told me I shouldn't drive it, but i'm driving it untill they figure it out.

Funny ... my ESP light came on the other afternoon. I shut off the engine and restarted it and the ESP light went out. Strange!!! Have to take the Nitro in for it's first oil change next week so will talk to the service department and have them check it out.

Steering Angle Sensor

Thought some members here might find it interesting to see what the steering angle sensor looks like. The sensor is incorporated in the clockspring which mounts behind the steering wheel. The picture attached is the clockspring disassembled, just showing the SAS.

What's interesting to see is what is causing these sensors to fail. If you look closely at the light pipe there are tiny white specks visible. This debris is created by the code wheel rubbing on the light pipe. The debris which ends up on the camera limits its ability to read the steering wheel location causing intermittent DTC's or failure of the sensor.

So is this what is causing all the intermittent problems reported by the folks in this thread?

Is this sensor used in any other Mopar or Jeep vehicles? Is there an improved sensor to replace this bad design?

That particular sensor came out of a 2006 Jeep Liberty. It is also shared with the Durango. I don't recall the part number. The parts lookup show they are different part numbers, the Liberty and Nitro. However, Chrysler seems to like renumbering parts.

I cannot say this is the cause for the problems members here are experiencing. Each individual owners issue needs to be properly diagnosed by his/her dealer.

Also a lot of parts crossover so this problem could exist in the Nitro if it is the same design.

Are these SAS units subject to malfunction due to condensastion on the optical parts?

I know that condensation caused problems in Chevies with the Optispark ignition which had an optical trigger--and shutter wheel similar to this.

If so that could explain the intermittent problems

Too early to say. ESP/BAS is fairly new for Chrysler products with the incorporation of a steering angle sensor.

ESP,living with the problem for now

Sounds as if someone is looking into the problem. Mine still comes on and off after it was so called fixed. But maybe a recall soon?

 

[RETPSP]

I had/have an intermitten BAS/ESP light(s) with my other "Chrysler" ride. Dirty tone ring or out of adjustment wheel speed sensor. I will let NitroTech be in charge of this thread.

Noticed the other day, while sitting and waiting at a stop light in my charger the esp/bas light came on too, then after driving for a bit it went off. So its not just the Nitros right?
