adjusting the tps how do you know its in the right place

[Turbo Habanero]

So I'm throwing the Tps code I think 52 also 71 egr code. So I need to adjust the tps and I'm not sure how to know you have it in the right spot. I've adjusted the tps and cleared codes they come back 30-50 miles later any help will be greatful I don't have internet ATM so I use my phone it's to hard to check out the tsrm

Doesn't sound TPS related...

 

[Turbo Habanero]

Hmm what else should I check out. Only thing I can think of is the little filter on the egr that goes on a vacuum line is missing

 

[jetjock]

Hmm. If it were me I would check out buying an actual manual...

Yeah its a android. And that's kinda ridiculous LOL. Ethier way I have no idea why the car is throwing these codes

Jeez, Toyota went to a lot of trouble to build in self-diagnosis, so the owner can then look up the code and find out what to fix. Seems almost straightforward?

except that everything its telling me that is wrong seems to be okay....

Anyway my original question is how to Know you have your tps adjusted right... i dont see this self diagnosis helping me much on that at the moment... and the only reason im asking this is because the code says its a TPS problem.

While there are a few ways to cheat it's usually set using the procedure in the manual. When the results spelled out in that procedure are achieved it's set correctly. Not sure why you're unable to grasp that.

It'd help if you told us exactly what codes are present. The ones you wrote in the first post have nothing to do with the TPS.

Sorry its just typo on my part its code 51 and 71 TPS and EGR related.

51 = turn the AC off...

71 = ECU not getting the proper temp from the EGR temp sensor (only on Cali models) You either have it disconnected, you removed the EGR, or you have a true EGR issue.

 

[Turbo Habanero]

um A/C i have made sure is off.

EGR is still on the car and it is a cali car.. i didnt ever have these codes be for i did the head gasket i have gone over the car time and time again and everything seems right.

Only one thing is off and its the VTV and Filter that comes off i believe its called a Dash pot diapham? I seemed to have lost in the rebuild...

Assuming that this is not an automatic with a bad NSW, then 51 would be a TPS issue (what he originally posted was 52 which is a knock sensor problem, which is why everyone is confused). Here is how to adjust it...

Nsw?

 

[3p141592654]

neutral-start-switch. If an automatic is not in park or neutral, you will get a code 51. If the switch is faulty, you can get this as well. Other causes of code 51 are the A/C on, and the TPS IDL switch not adjusted properly.

 

[Turbo Habanero]

ok so i adjusted my TPS code 51 has gone away by itself (I.E didnt have to reset codes) 71 still there. Still havn't reset codes tho.

71 is the EGR temp sensor. You must have a California spec car. Its not going away by itself.

can i just put on a egr block off plates and eliminate it all completely?

 

[Poodles]

No.

WHy not hook it back up. It doesn't hurt performance, and lowers EGT and detonation risk at mid load.
