Hi,
I have a S60 with a TPS problem. The sensor is a Penny & Giles.
Picture of the logging:
I've tried two sensors so far and still the same problem. The throttle stop/start is correct as far as i can see.
Could it still be the sensor or something else?
Regards
Erik

Re: S60 and TPS problem

Re: S60 and TPS problem
looking at the log it looks like the engine has gone from 5000rpm to 5500 rpm without touching the throttle or is the logging backwards
Re: S60 and TPS problem
I did a short video of it on the Dyno today. When hitting the pedal fast and to 100% throttle it "pumps" the engine like on the video. On the PC you till see that the colorize of where it is in the map disappear.
I do have somekind of same problem if i try to hold 10% TPS as well.

Any idee of what this could be?

Re: S60 and TPS problem
Perhaps a bad wiring loom / connection to the tps.
Try the real time chart to view things like this

Re: S60 and TPS problem
Solved the problem today. After TPS change, i did not adjust the value on fully closed throttle. It was 62 on idle. Adjustet to approx 100 on fully closed. Then did the throttle learn. Now the throttle is 3% on idle and not 0 it was before.
Thanks!
Thanks!

Re: S60 and TPS problem
A good reason to have your idle at 0% makes it simple to change a faulty tps, how you have it now is a pain to set up, particularly in the field.
You must have somehow had it set at -20% so it just shows as 0% not sure how that would make it jump around however unless the -20 point is within the 'tps failed zone' and the ecu was substituting the tps fail value located in general engine settings.
If so you will have seen a building count in the diagnostics screen showing throttle pot failed. All the tools are there to help, just need to look at them
