Mox32r Member 34 Member For: 1y 11m 9d Posted 24/02/23 01:32 AM Share Posted 24/02/23 01:32 AM Hey guys. Just wondering if anyone can help me with info on checking the tps with a multimeter? I have found vids and info on the 3 wire sensors but nothing for 4 wire. Well found 1 site but its for Mitsubishi eclipse. Would it be the same as that? Or do they differ vehicle to vehicle?

Mox32r Member 34 Member For: 1y 11m 9d Posted 24/02/23 06:56 AM Author Share Posted 24/02/23 06:56 AM I no longer even have a laptop mate. It umm fell apart 😕. I have the forscan app which I paid for and an obdlink mx+. Could I see that info in that? Pretty sh*tty support they have but. I can't even join the forum or contact them. I had to contact them via google play and still no reply Link to comment Share on other sites More sharing options...

I'll go and measure mine with a multimeter tomorrow and tell you which wire does what etc. What's wrong with the car that makes you want to check it?

Mox32r Member 34 Member For: 1y 11m 9d Posted 24/02/23 07:46 AM Author Share Posted 24/02/23 07:46 AM Oh sweet thanks mate. That would be great. Has a bit of a miss/rough idle, and some of the codes I have retrieved point to that. Made a crude smoke machine to check for a vacuum leak which I can rule out. The rough idle was present before I changed the coils out, and in doing so I found that no.1 and 3 spark plugs were completely submerged in oil, but after the gasket fixes and Coil + plug change the miss didn't go away. I need to pull the coils and plugs again to check but just checking things along the way. And I figured checking sensors with a multimeter is an easy way to work out whether they need replacing or not Link to comment Share on other sites More sharing options...

There is a failsafe in the pcm that activates when there is anything wrong with the ETC (electronic throttle control) system. This includes the tps and throttle pedal. It has several degrees of activation and in a wide case scenario will shut the engine off. For info purposes there is nothing in the throttle body except a spring, a plastic gear, an electric motor with the tps on the side. All that aside, I'll check mine tomorrow but in the interim you can clean your throttle body, if there is a carbon build up it can hold the blade open further than it should be. This will add more air at idle which will raise the rpm, however the idle speed is mainly controlled via spark adjustments, so it could pull a whole bunch of timing making it idle like sh*t. Lol last paragraph, you really need to scan for codes and also need to use a scanner/logger to see what the engine is actually doing when this issue is present.

Mox32r Member 34 Member For: 1y 11m 9d Posted 24/02/23 10:00 AM Author Share Posted 24/02/23 10:00 AM OK so I thought it could be on the way out making problems. I did clean it when I did the Coil packs, it didn't really even need a clean but it got one. I think I need to just pull the Coil plugs off when it's running and see which if any make a difference. I will upload the screenshots of codes I have pulled. I cleared them each time and these are what come up after I have given it to it. If I just baby it the only code that comes up is the a/c one because it's out of gas. I have a new turbo to go as I was having the over boosting and bypassed the boost solenoid which helped a little but not a great deal, and the turbo shaft has a lot of play. OK so I don't know how to upload an image lol Link to comment Share on other sites More sharing options...
Mox32r Member 34 Member For: 1y 11m 9d Posted 24/02/23 10:14 AM Author Share Posted 24/02/23 10:14 AM OK so these were the codes. B1262, B2014, P0532, P1227, P1270, P2105, P2110, U1900, U2196, U2197. Cleared them then next time were B2005, B2006, B2139, P0196, P0532, P1227, P1260, P1285, P1299, U1147, U1900. Then P0121, P0121, P0124, P0223, P0224, P0532, P1270, P1474, P2110, U1900. These only come up after giving it a bootful. The only one that's there no matter what is the a/c as it needs gas. The Abs I fixed by cleaning the sensors and the ones to do with the fan are because I bypassed the really with a switch to see if 8 could get the thung to run cooler but tuning the fan on sooner Link to comment Share on other sites More sharing options...
