Title: TC and EML
Post by: megaomega123 on 02 August 2010, 12:21:03

I have had intermittent tc light for about a month with people saying abs ecu is on way out.
I get the tc light when I accelerate over 5000rpm, then if I continue to accelerate I get the EML which is giving code 21 (throttle position sensor high voltage).
I can only presume this is related as the tc must use the tps.
Could this be as simple as a new tps rather than abs ecu?

Ever so slight kind of power lack just before the tc light comes on.

well it doesnt sound ECU related.

as you have a TPS error, could be worth swapping out.
Certainly sounds a good starting point with the info youve given.

The rev counter is also a little sticky. Where is the TPS located? How difficult to change and how much roughly?  :y

Seem to have got to the bottom of this problem. The TC light does not immediately point to ABS ECU. I unplugged the TPS with engine running and the TC and EML came on with code 21. This is the exact symptoms I have been getting, along with a sticky rev counter. Have ordered a new TPS for £12 better than the £800 quoted for ABS ECU.  >:(
