Thread: Intermittant loss of throttle response Puma 2.4

Any idea what a TPS costs? Thinking about getting one for the the toolbox if it can die and leave you stranded.

They come in at about £100 in the UK for the genuine LR ones.

has anyone activated it with a programmable Xgauge code yet ?

Crude, but possibly sufficient to diagnose an issue?

Check the green and white wires in the back of the plug that connects to the turbo, may be broken and contacting intermittently, was my problem.

same thing happened to me again today.. no power on 4th gear.. back down to 3rd and its fine. after a couple of minutes, no power at all.. and it comes back again..

talk about stress driving down the fwy. went like this for about half hour then engine suddenly stalled / died while I was still moving at about 40kph+ in 3rd gear.. thankfully wasn't on the fwy. restarted the engine and it was fine again.

going to bring it into the workshop tmr.

Thanks for the comments. I'm just back from my 2000km trip, and it hasn't played up again since the first 2 occasions, just before my trip.

I did check electrical connections to the throttle position sensor before I left, as well as relays under the drivers seat as suggested. I guess that doesn't throw much light on it really. My gut thought TPS, but my gut isn't always right either!
