    I start my vehicle and press the accelerator and the vehicle dies. when I get the vehicle started and to warm operating temperature the vehicle runs with the rpms above 800. Then when the accelerator is released the vehicle goes to a rough idle and evenually shuts off. I unpluged the tps and the rpms doesn't change. Sometimes the temperature gauge goes all the way over and the temperature light comes on and I shut off the vehicle before it overheats.

Their is a few ways to test the throttle position sensor. One way is to hook up a scaner and go to the data menu. Their will be a place in the menu that will say tps % and tps v. You want to watch the one with the v. The v stands for volts from the t.p.s. Basicly the t.p.s. is a variable resistor. The further you depress the the throttle the more or less volts you get from the t.p.s. The voltage should gradualy go up as you slowly depress the pedal. If the voltage jumps around then the t.p.s. is bad. Another way is to get a volt meter and remove the connector to sensor, touch the contacts on the sensor with the sensor still hooked up and have a friend depress the pedal slowly.

You can find the tps on the opposite side of the cable on the throttle.

Please contact me if you have any more questions or comments.

Thanks, Charlie

Did you do a fuel pressure test with a fuel pressure gauge ? The throttle positioner ? ? ? ? It's TPS - throttle position sensor. I suggest you take it to a ASE certified repair shop . Or go to youtube an check out some basic diagnostic trouble shooting videos . What year , make , model vehicle do you have ? You should have a factory scan tool or at lest a professional grade one hooked up an have engine sensor data parameters looked at . If you don't know what these are , I strongly suggest you take it to a repair shop.

Which one should I replace first the throttle positioning sensor or IAC sensor it's getting gas when when I give it full throttle it stays running but barely

You replace nothing

Only when you understand both the system with a problem
& how to test it & it's components & a component fails,do you
replace the parts (common sense)

Runs Fine but the power is down


PO121---ETC Throttle Position (TP1) sensor Circuit Range Performance

PO505---Idle Air Control System Malfunction

PO2106---Throttle Actuator Control System-Forced Engine Limited

Just take it back to whom ever did the work,they are totally
incompetent or don't know Fords

These are not easy to diagnose but I do all the time in my
driveway,with all the factory manuals & professional tools
& test equip,but no reason this comes up on fords & lincolns
& a dealer in most cases can't resolve

Take too long to explain & you wouldn't grasp it anyway

Just dont replace parts

Any suggestion of parts come back with details

My 1996 GF1 impreza just wants to run at 2000rpm. This happens when i engage the gear. When i disconnect the throtle position sensor,everything cools off, adjusting the same sensor while connected...


From your description it looks like you have a defective TPS (The TPS is the position sensor on top of the throttle body that you are disconnecting).

Signal from the TPS is very important for different vehicle's functions. Among other thing the TPS output is used by the electronic ignition system to determine the fuel mixture being injected and by the automatic transmission to determine when to change gear. In your case the transmission was probably not shifting into higher gears, for that reason the engine was not revving above 2K rpm.

The TPS can be tested reading voltage at its terminals while someone operates the throttle pedal. Voltage must increase/decrease smoothly and stay in range, otherwise the TPS must be replaced.

As said at start your problem is likely a defective TPS. The fault is quite common and it is fixed replacing the TPS.

Starts but won't stay running...when reved it will

checked the idle control valve next to the throttle position sensor? Remove it and spray the passageway out with carb cleaner, then clean off the valve end (don't turn it while cleaning) Don't loose the "o" ring on the part either.
Before doing that though make sure all the vacuum hoses are attached and not cracked or broken.
Other than that, you may have a bad throttle position sensor or map sensor. Check (test) them before buying...they are expensive and you don't want to buy stuff you didn't need! You have the advantage here. I can't see the car. You can, and need to test!!!
