105 JTD - Where is Throttle Body / Throttle Potential Sensor

I still think I have a performance issue and there are definate flat spots, its like I can get max performance with half throttle pedal action, pushing any further doesnt seem to make much difference.

So wanted to give this sensor contacts a clean. It worked for my coop but that time the injector light came on and diags pointed to the TPS, this time in the Marae , no injector light so its a long shot, costs nottin to try

I mean Position Sensor . What was I thinking although it can make sense.

Isn't it the mass flow meter that goes wrong on the JTDs which makes them sluggish?

Re: 105 JTD - Where is Throttle Body / Throttle Potential Sensor

It could be that but I had the MAF out of its casing tonight and gave it a clean with alcohol. Looks like new now. What is there to go wrong ? I peice of wire that gets dirty ?

hmmm. I did the reset on the ECU afterwards and let the car idle for 5 mins as per the BOO instructions. Didnt seem to make much difference but then when I unplugged it that didnt either so it may not the the MAF at fault.

So back to the question ? Where is the Throttle body , where I can rev the engine without sitting in the car, the TPS is usually around there if there is one.

Cheers

Re: 105 JTD - Where is Throttle Body / Throttle Potential Sensor

think the jtd is drive by wire, so there is no throttle you can manualy pull to rev it up.
