Throttle position sensor. 164 Q4 with EGR.

by **Romuald** » Tue Nov 14, 2017 3:50 pm

Hello! I have a problem with idling the engine. I'm worried about the throttle position sensor. What should be the resistance at the contacts with the throttle closed? 164 Q4 with EGR. Thank you.

Please, if possible, measure the resistance on your sensors if your machines have no problems with the engine. Thank you.

I will have a look next time I am in the garage, but that might not be before end of next week.

I forgot about this

I will not be in the garage until beginning of next year, but maybe you figured it out?

No

The motor works very poorly. There was an icon "check the engine" in the form of an injector. If you increase the speed by pressing the pedal, the "check engine" icon disappears. At the moment I can not find a working program for diagnostics.

I thought that the check engine light was not connected in the Q4, it isn't in mine.

Have you tried unplugging the air mass meter? What about spraying start gas around the intake pipes to see if idle changes?

Are you not able to download Wilco's diagnostic SW? I just tried downloading from the first page in his thread without problems.

I am going to the garage this weekend, will try to remember measuring this! Even though it is without EGR, I think it is the same part.

Have a look at the attached docs, this should provice the info you need.

Hello! Thank you so much! Symptoms indicate an air mass meter. In two weeks I will receive a new flow meter. I had doubts, since I changed it recently, but it was very inexpensive, so, probably, immediately after installation, it stopped working.

The reason is not in the flow meter! I did not put the gasket correctly ))

A simple fix - when you know what to look for! Glad that you found it

I clicked on your photo and got redirected to a not so nice site...!!! I suggest you just add photos...
