Thread: TPS again?

Tell me it isn't so.

I think the TPS I fitted two months back is a dud.

I replaced the original TPS as I was getting surging on a light throttle. The surging went away with the new repalcement TPS. Britpart I think was the make.

Lately, well actually only happened three times, if a put my foot down more than usual, say half way down, accelerating quite hard, it will just die. It will stay like that until I move the accelerator pedal. Then it will charge on like normal.

I usually drive on a very light throttle, gawd it's heavy enough on fuel, so I don't know how long it's been like this.

Otherwise she runs fine. Idle tends to hang a bit when hot, but hopefully the new idle valve I have ordered will solve that.

Any suggestions?

Thanks

I went thru the whole system again and couldn't find anything wrong.
Plugs look good. MAF setting is exactly where I left it.

The intial reading on the TPS was 0.34v exactly as I set it when I put it in. However as I slowly opened the throttle the reading would increase until about half throttle where it suddenly dropped to 0.09V. A few tests repeated this.

Swopped the TPS and the problem disappeared.

So now to see if I can get it replaced under warranty.

In Afrikaans there is a saying "Goedkoop is duur koop" basically going cheap costs more in the long term.

Thinking about it now so far I have only had problems with non genuine LR parts.
