SOURCE: throttle position sensor

Sounds like you have a vacuum leak somewhere on the engine. If the tps was bad, it would set a code and the check engine light would be on. Also, check your air tube that goes to your throttle body - make sure the hoses are connected tight and the tps is on the throttle body down on the front of your engine where the hose runs down to it. It's not really that hard to get the throttle body off. That would be the best way to change the tps - to take the whole throttle body off and put new gaskets on and tps on it. Hope this helps you out. PHil

SOURCE: Crankshaft Position Sensor

The crank sensor is on the front of your engine behind the harmonic balancer. You will need a balancer puller for a 3.8 and a crank sensor alignment tool to do this lob.

SOURCE: replacing bad camshaft position sensor

  1. Disconnect battery ground cable.
  2. Remove water pump pulley attaching bolts, then the serpentine belt and water pump pulley.
  3. Disconnect sensor wiring connector and remove sensor retaining bolt.
  4. Twist and pull sensor to remove.
Reverse procedure to install and prior to installing new sensor, lubricate sensor O-ring.

It is located under the water pump. Make sure when you remove the sensor that you rotate the crank shaft and look in the hole to make sure the pick up magnet is still in there. Sometimes they come loose and cause a no start or long crank. You will need to have the code cleared still.

SOURCE: Missing, stalling Pontiac Sunfire

The OBD II code for P0400 is Exhaust Gas Recirculation Flow Malfunction.
I'm sure the only thing you have left is you may have to replace the EGR valve or check for any leak from the vaccum lines going to to EGR valve.

SOURCE: 1999 firebird v6. Have had problems with

$900? $850? You could get a new engine for that price.

If the car has this condition only when it is very cold then I suspect that during that time it is operating in a condition controlled by an engine temperature requirement. When it is cold enough it will continue to run the fuel management in what is called "open loop" mode until it is warm enough. It needs to be warm enough to allow the oxygen sensors to properly read the oxygen level of the exhaust gasses and send that information to the computer, which will then calculate and command the proper air to fuel ratio. The other important reason is that the exhaust gasses must also be hot enough to activate the catalytic converter contents to break down the combustion byproducts, which is about 650F. When it reaches the minimal operating temperature requirement, the fuel management program then switches to closed loop fuel control...at that point emissions are the least and fuel economy is improved.
A new throttle body will not solve that problem. A higher temperature thermostat or a higher coolant to water ratio will help.
By the way...a throttle body for your car is no where near $900...not even half of that with even the MAF sensor included and that's $150 by itself.

Buick Enclave will occasionally at a stop rev up to between 2000-4000 rpm


Three possible reasons for this are
1. You have a vacuum leak
2. The throttle position sensor (TPS) has gone bad
3. The idle air control valve is bad or blocked up.

Where is the throttle position sensor on my 2000 Toyota celica gt? What would be signs that the TPS is bad on my car?


It is on the throttle shaft,2 little bolts . Should have turned on the check engine light if it's bad ,would stumble and possibly die on acceleration,best to get it scanned at a parts house to see if it has a TPS code or not

2006 chevy monte carlo 3.5 v6 tps replacement


A THROTTLE POSITION SENSOR (TPS) is usually located on the butterfly spindle so that it can directly monitor the position of the throttle valve butterfly.
Throttle actuator control(TAC), that code comes from that part of the system too.

1990 Chevy Lumina showing codes 12 and 21. What are they?


code 12 flashes any time trouble codes are pulled without the car running. It is normal and think it has something to do with not receiving distributor pulse.

Code 21 has to do with the TPS (throttle position sensor) voltage being to high. You'll need a DVOM (digital volt ohm meter) to check this out. Unplug the TPS sensor and check for 5volts on the grey wire, and make sure the black wire has a good ground. If those check out plug the sensor back in. Back probe the blue wire. you should see around .5 volts with the throttle closed. The voltage should go up smoothly as you slowly open the throttle. At wide open throttle the voltage should be around 4.9 volts. If any of the above three are not true I would suspect a bad throttle position sensor.

I have a 1988 pontiac firebird with a 2.8 v6 fuel injected engine that displays code 32 and 34. We have changed the plugs, plug wires, rotor, and dist. cap and have also replaced the mass air flow (maf)...


Check throttle position sensor (TPS) is a sensor used to monitor the position of the throttle. The sensor is usually a potentiometer, and therefore provides a variable resistance dependent upon the position of the valve. The sensor signal is used by the engine control unit (ECU) as an input to its control system. The ignition timing and fuel injection timing (and potentially other parameters) are altered depending upon the position of the throttle, and also depending on the rate of change of that position. For example, in fuel injected engines, in order to avoid stalling, extra fuel may be injected if the throttle is opened rapidly (mimicking the accelerator pump of carburetor systems). the cost about 50-75 bucks.
