SOURCE: idle malfunction

You need to replace your idle air controller (IAC). IAC basically opens and closes the throttle at idle so it stays at constants RPM.  Hope this helps.  Thanks for an honest rating and for using FixYa.

Car does not run ,I check the code ,it is P0700


Because it is not starting, you should replace the Crankshaft sensor (above the oil filter, back of the engine)-it will cause a P0700-I have a 99 SL2, 178,000 miles


DTC) CODE # P0700....Transmission Control System (MIL Request)
Translation: Transmission Control Module (TCM) Malfunction or Failure. P0700 Information Code The Transaxle Control Module (TCM) monitors the malfunction of sensors and actuators relating to transaxle control. If any malfunction is detected, the TCM informs the PCM by sending a signal (P0700 code). P0700 means that a code has been set in the TCM. This code is for information ONLY. If this code is present, check for transaxle codes. So basically, the P0700 code is telling you to check the TCM for a transaxle DTC. The TCM can not turn on the check engine light so it has the PCM do it. The dealer probably saw the code P0700 and went to the TCM and pulled out the code stored there telling them the Transmission Solenoid Assembly (TSA) is bad. This is a good example of understanding what the codes actually mean. If the manual you looked at said the TCM is bad and to replace the TCM when you see a P0700, then it is wrong.

What does the fault code 0483 mean for a 2005 dodge ram 3500?


computer confused by cooling fan voltage/current level. Is the fan working? If yes, may have a short. If no, try hotwiring to battery to see if it's good. If fan works by hotwire, suspect relay is bad. Check all wiring before buying any parts. Relay does not click in until engine is hot. Let me know if you have more questions.

Trouble code po483 and po573, what are they?


P0483 Cooling Fan Rationality Check Malfunction
This code is set when the Engine Coolant Temperature (ECT) sensor signal fails to rise above 15 mV (~1°F) after 2.5 minutes of operation. You probably need a new ECT sensor.

P0573 Cruise Control/Brake Switch A Circuit High
This can be caused when the brake switch is set too high. Possibly a faulty brake switch.
