The computer controls all sensors. Their maybe a fault in the computer that is making the engine idle high. Go to your mechanic and have him scan for problems. (error codes). Good luck.

SOURCE: Check engine light is on and high idle (1500rpm)

Some times the E.G.R. will stick half open. This will make the engine surge or have high idle. Try replaceing the E.G.R. located under the upper intake. Do not go with after market E.G.R. The spring in them are to powrefil and the E.G.R. wil not open. Also try replaceing the O2 sensors. This could give the engine more fuel thus a higher idle. Some vehicles the T.P.S. can be ajusted, do some checking to see if yours is adjustable.

Please contact me if your problem presists.
Thanks, Charlie

You are really onto it! Either the TPS or the cable from the peddle. Do check the cable first. Frankster016

It sounds like you have a vacuum leak or intake gaskets leaking. Try this. Start the engine and let it reach the idle it want to go to. Get you a can of Brake Clean and spray it around the intake manifold (it on the top center of the engine, you may have to removed a plastic cover) If the engine idle changes up or down then the intake gaskets are leaking hence your vacuum leak. I hope this will help you.

SOURCE: my 2000 ford focus se read p1120. already replaced

does your engine idle fast or slow? You may need to clean the idle selonoid or the throttle body. They carbon up and stick.

Timing, engine control module, throttle position sensor, air flow meter. Run a diagnostic test to see what codes it shows so you can determine the exact cause.

2001 ford focus se sedan revs to high after replacing icv and tps


It sounds like the TPS was installed improperly..It has to be set in place with no tension on the spring loaded mechanism...This will cause the throttle to rise...I don't know what problem you had before replacing these components but nothing should magically go bad while doing it unless it is a faulty new part...Try removing the TPS ..,INSPECT it to see the plastic lever operation is in correct timing with the lever it is mounted to ...Look close with a light to see what I am describing then carefully connect it....I've seen it happen before...If not the IAC..( idle air control sensor )..will cause it to have a high idle if it is bad....),,maybe it was accidently disconnected .....GOOD LUCK..

My idle is low on my 2001 ford focus se and it is a stick shift so my car dies when I come to a stop unless I have my foot on the gas just a bit. how can I turn up the idle? Help please.


The idle is computer controlled. It takes a reading from the crankshaft position sensor as well as the camshaft position sensor along with basic information from other sensors, processes it and sends a pulse signal to the intake air control valve (IAC). The IAC valve is positioned to allow air to bypass the throttle plate and control the idle. Once the throttle is opened the IAC is commanded on 100% until the throttle is closed. In short, a scan of the pids needs to be done to determine whether the processor is commanding the IAC on properly or if the IAC just isn't responding properly.

A scan for codes can be done but many times an IAC won't throw a code so the sensor pids really need to be performed to determine the root cause.Good luck.
