TD5 Throttle Problems

Hi All,

I'm hoping someone can help me get a response from the throttle in my 2003 TD5. I bought it from the MOD a few years back as a non starter (compression issues) and have since rebuilt the engine and it now starts. Upon starting for the first time it has become apparent that the throttle pedal does not work. One of the first jobs I did (a few years ago) was to remove the mess of wiring under the drivers seat which included some left over remains of what appears to be a hand throttle. I've recently double checked the wiring and it all seems to be correct.

Is there anything else that has to be modified when installing a hand throttle that I now have to remodify to original? OR is it likely to be an issue with the throttle pedal and pots?

Many thanks for your help

Archie

Remove the pedal and check what part number is fitted.

Also the part number of the ECU, you may have a mis-match between the ECU type and the pedal type.

It's a 2003 so should be an NNN ECU with a 3-track pedal, but who knows what it's ended up with from the MOD when sold, or what spec the MOD had in the first place.

Or just switch to 2 way pedal first - with diagnostics in engine ECU. "Drobek" = The Small One - Discovery 2, "Blufínek" = The Blue Thing - Defender 130, and for me at least Ford Mondeo

Hi Martin,

Thanks for your reply.

The pedal part number is G2G29AF98481. I cant seem to find any info on that anywhere, do they have individual part numbers for each pedal?

Where do I find what type the ECU is? The label on it gives a number starting with NNW***, is that what I'm looking for?

Thanks

On the ECU there will be a part number starting MSB or NNN (not NNW)

The pedal should have a yellow sticker with something starting SLC

Found the pedal part number, but as far as I can see the ECU code starts with NNW. I've attached some photos, is that the right code?
