Question about 2003 Toyota Tacoma

1 Answer

Engine idles high and trans doesn't shift properly when cold

Is this normal? I've had this problem since I first bought the truck.
The service manager told me it was normal.
Does anyone else out there experience this same problem?

The engine is supposed to idle hgh when cold, to reduce emissions. The transmission shifting that you speak of...are you talking about the final shift? The final shift does not hapen until the coolant temperature reaches 177 degrees F. This too is an emission-reduction pre-programming. In short, your Service Manager is not leading you astray; he is quite right. I tell my Taco customers the same thing. Also, this is all in the basic program of the ECU (computer); and cannot be changed. I hope that this helps you out.

How can i slow down the rpm so the trans. could shift properly


What size of engine do you have. Does your engine idles high. Do engine idles high all the time or just when is cold?

Revs high


If the idle speed is normal until you shift into a gear, the idle air control valve is probably raising the idle speed. Try unplugging the iac motor at idle then shift into drive.
If the IAC is raising the RPM the computer controls it, so for some reason the computer thinks the RPM needs to go up. I am assuming you do not have a check engine light on or you would have checked for trouble codes.
Just for the record, I am showing the same IAC for both transmissions on a 2.0 engine code 3.
Is it possible the battery was disconnected and the learn process needs to be done for the computer to know where normal idle speed is ?

I have a revving sound on the engine when I shift gears. The rpms are not high so I am baffled. This is a ford f-150 6 cylinder 4.2l , man trans. It idles normal


Sounds like you may need to replace the TPS (throttle position sensor), that will cause the idle not to fall in between shifts.

My 2000 gmc sierra z-71 has started idleling at about 1300 rpm after driving for a while. when i turn it off and restarted it would idle fine for a while then start idleing high again. it is getting to...


I assume the check engine/ service soon light is on. Commonly the MAP sensor is the culprit, but can be TPS, CSS, even a buggy O2 sensor. Only way to be sure? (light or not) is to scan it.

Car not shiftting right. The check engine light came on and we pulled a code of P0507 ''Idle Control System RPM high''. The throttle body was cleaned out with throttle cleaner and the light stayed off for...


THE IDLE SPEED SENSOR SOUNDS LIKE IT IS FAILING. THE IDLE SPEED SOLENOID CAN PREVENT THE TRANS FROM SHIFTING AT DESIGNATED RPM'S. THE THROTTLE POSITION SENSOR WORKS IN CONJUCTION WITH THE IDLE SPEED SENSOR TO TELL THE COMPUTER THE DEMAND FOR FUEL AND THUS SHIFTING THE TRANS AFTER THE RPMS HAVE REACHED ALMOST REDLINE. TRY CHANGING THE SENSOR AND YOU WILL HAVE SOLVED THE NO SHIFT PROBLEM. THANKS FOR USING FIX-YA AND FOR AN HONEST RATING. PLEASE KEEP ME POSTED. GOOD LUCK
