I have a 2006 r53 that the check engine light came on. Dealer said code read a bad gas pedal, which would cost about $550. They couldn't guarantee that this would fix the problem and said after replacing that it still might need a wiring harness for another $1,000. The car has 73,000 miles on it.
I had the code cleared but it came back on and the car goes to limp home mode periodically
Does the gas pedal and wiring harness diagnosis sound correct.

 

Do you know anyone else with an 06 Cooper S? If so try swaping out the pedals--only 1 clip holding it in and the wiring connector. 5 minutes tops. clear the codes and see what happens. Part # for a new one is 35426786280 and can be purchased for under $120 at ECS. If the replacement pedal doesn't work then it may be the wiring harness--check the connector for corrosion before swaping in a replacement pedal.

 

Thanks for the quick reply
I don't know anyone with an '06 but will try cleaning the contacts in the morning. That would be great if that solves the problem

 

Sometimes you will get a throttle position sensor code , think its location B for the floor for the error code. If MINI ran the computer and it said the floor accel position sensor , its most likely it. Do you have a manual transmission or an automatic, there are two different part numbers ?

Thanks

 

Bet you can find a used part for significantly less money.

 

Any idea if a "sprint booster" or a knockoff/clone is installed....
If it is...try uninstalling it...
If the dealer says "try a $500 part" but it might not work....I'd run....especially since the part cost is only $115!!!
Think your dealer is picking your wallet.....

 

Thanks for the replies. The car is a 6spd. I pulled the pedal off today and cleaned the connections. Put it back together and it works great. All warning lights went out. Not sure how long it will last but even if I need to replace the pedal I see how easy and inexpensive it is
Thanks again. I think I may have saved myself about $600

 

Good to see it worked out for you!!!!

 

++1
Good to hear it is working!!

 

Glad if worked for you, I had the same problem once and I did clean the connections but it returned with the CEL throttle B location and then I just swapped in a new one. Hope yours last and good luck.

 

I would suspect that it is actually the pedal and not the contacts but hopefully it will continue to work great for you.
I just had the same problem, occurred twice both times after having the pedal in a single location for some time (cruising on the highway) then coming to a stop the car stalled and went into limp mode. Once an engine restart corrected the problem the other time required a battery disconnect to clear the problem. Just information in case it happens again so you can get going again without a tow.

I believe the pedal rheostat wiper and coil tends to wear over time and become intermittent at certain spots (dead spots). I suspect if the pedal stays in a dead spot too long the computer goes crazy and thus into limp mode.

If I was you I would purchase a pedal and install the new pedal, very easy to install, so you do not get stuck on the side of the road or in a dangerous situation on the road when the car unexpectedly dies.

 

Yep, had it happen twice to me after the clean , then replaced new and ok since. Scares the crap out of you, get the stumble then the Check engine light and read the code , throttle position sensor. Throttle does nothing. makes it feel like there is something majorly wrong with the engine, been there done that.

 

Looks like I'll have to order a new pedal. Lights came back on today. At least I know how how easy it is to replace now

 

Yea, been there done that. Glad I could help.

 

Sorry to start something 9 years old, could you elaborate on the problem you had? I'm having a problem where the throttle pedal becomes unresponsive when I'm driving randomly but no check engine lights. I restart the car and the problem is gone.
Would you suggest a new pedal?

Thanks 👍

 

Yes, Its the sign thats somewhere on that electrical plate inside on the the sensor is worn, when you hit it, you get the cutout. Its will not through a CEL until its a permeant error. Get it replaced. Otherwise you will be stuck on the side of the road.
