4 CE codes, idles, doesn't drive

[Sideways_bob]

Alright this is a tough one. Car ran fine besides a vacuum leak, no codes, ect.

Removed the manifold, ypipe, and tb to clean carbon out of it.

Put everything back together and this is what I get. Fires perfectly up to idle then dies. I have to be full throttle to get it to run at all. I hear misfire.

I have checked my vac lines through the tsrm they are fine
Brand new plugs, Cleaned the plug valley and runs a little better
Brand new tb, manifold, and ypipe gaskets.
Grounds are all connected

Im getting codes
14 - ignition signal
22 - Coolant temperature signal
24 - Intake air temperature signal
41 - throttle position sensor

Now the car will idle won't go over 2k rpms
Sounds like it's missing
Ticking

:3d_frown: Supras and their codes and bhgs and watnot


I have a ohm meter, i dont know how to check these signals and what setting to have my meter on. if anyone could help out thatd be amazing.

Please help out!

This says how to check the tp sensor, but
1. what setting should i have my meter on?
2. How do i adjust the tps if its not getting the right ohms?

Update code 22 was the sensor being unplugged, I pluged it back up

code 14 - I relocated the coil pack, and 2 of the plugs are shattered on the white part, I'm going to get the 2 new plugs, and check the ground on the coil and the wires

code 24 - I changed MAFs with a friends supra hopefully this might play a role, thinking about switching back to my old one

code 41 - TPS female harness shattered during bhg fix. Just need to figure out what wires go where on the TPS and hopefully that will fix it

Ill update once i get all these codes cleared. If anyone can help me figure out What colored wire go where on the tps I can get the tps code cleared.

Sort of sounds like your harness is fibbed but it could be a multitude of other things. In all honesty, make sure everythings plugged in good and wiggle your harness around and see if it makes any difference.

Also, make sure your vac lines are routed correctly. I routed them wrong once and it gave a bunch of problems. Looked on a friends car and routed them up the right way, problem was solved. It's extremely easy to mess up your vac routing when you put everything back together.

Also, there is a specific way to reattach the TPS if you did take it off from the TB. You have to screw it in a certain way, if it isn't even it will not give the right signal and even if it's a small problem it will give a hugely wrong signal to the ecu and your car will run like piss.

Lastly check your idle valve. You might have messed with the factory screw.. if you did it will cause problems. Just make sure all it's not blocked and it is hooked up right.

Good luck, don't give up. Can be really frustrating, I've been there.:nono:

Idle problem = TPS. Got it fixed idles fine
Vac leak = EGR plate on manifold, never bolted it in *DOH*
Temp sensor = Was loose
Misfire = Cheap plugs, used better ones
Ticking = Misfire

All is well and it runs good, for a little while at least.

Good to hear.

It's the best feeling to have a problem then to do something that fixes it.
