A P0507 DTC trouble code may be caused by one or more of the following:
A vacuum leak Leaking air intake after the throttle body
EGR valve
leaking vacuum
A faulty positive crankcase ventilation (PCV)
valve Damaged/failed/dirty throttle body
Failed EVAP system Failed IAC (idle air controller) or faulty IAC circuit.
you would need to check these. some times its just a glitch in a sensor when the revs go to high. remove the code and see if it comes back. can activate this code if revs to high.

How do you know if your ecm is bad?


most likely the IAC valve is bad , which damaged the ECM also. Have replaced couple of ECMs for this code in 2003 pathfinder. P0507 is an ICS code , which is linked to faulty IAC valve., but the ECM is an issue also, most likely. Find ECM on ebay. and replace the IAC valve with new one.
Wait one minute, your model pathfinder also has giant recall for strut towers rotting out, so have your local dealer check your VIN for the campaign. if the car is rotted beyond repair in certain areas by the struts, Nissan will buy the car back and give you money for it. Check the vin with your local dealer.

Hy is there a code p0507? and how do i fix?


This P0507 code is one that's sometimes triggered on vehicles that have electronic throttle control. That is, they don't have a regular throttle cable from the accelerator pedal to the engine. They rely on sensors and electronics to control the throttle. In this case, the P0507 DTC (diagnostic trouble code) is triggered when the PCM (powertrain control module) detects an engine idle speed that is greater than the desired (pre-programmed) RPM. In the case of GM vehicles (and possibly others) if the idle speed is over 200 rpm higher than expected, this code will be set. A P0507 DTC trouble code may be caused by one or more of the following: A vacuum leak Leaking air intake after the throttle body EGR valve leaking vacuum A faulty positive crankcase ventilation (PCV) valve Damaged/failed/dirty throttle body Failed EVAP system Failed IAC (idle air controller) or faulty IAC circuit. This DTC is more of an informational code, so if there are any other codes set, diagnose them first. If there are no other codes, inspect the intake air system for air or vacuum leaks and damage. If there are no symptoms other than the DTC itself, just clear the code and see whether it returns. If you have an advanced scan tool that can interact with the car, command the idle higher and lower to see if the engine responds appropriately. Also check the PCV valve to see if it's blocked and needs to be replaced. Check the IAC (idle air controller) if equipped, verify it's operation. If available, try swapping in a new throttle body to see if that fixes the problem. On Nissan Altimas and possibly other vehicles the problem may be fixed by having the dealer perform an idle air relearn procedure, or other relearn procedure

Hi, I have 2004 Nissan Altima and Service Engine soon light is ON since last few days, today i went to AutoZone and then found Error Code P0507 So can you please suggest how to reset this light? and...


the dreaded P0507, have you had your throttle body cleaned lately? I did clean a neighbors TB while doing other maintenance things to it, and this popped up-and it was miserable getting rid of it. You have to do a 'relearn' procedure (about a million times or so, it seems) and DO NOT take it to a dealer-they will just charge you $100 and tell you to install a new throttle body (not cheap). They know this is a problem, and act like you have done something wrong for merely cleaning a dirty TB. It can and will go away if you do the 'relearn' procedure-read this post for information on how to fix it. it is just annoying but does not have to cost anything to correct. His took MONTHS to reset, but it did, and I did a lot of research on this and can assure you it is not what the dealer would have you think it is-they will try to separate you from your money for this code. read this:

2004 altima 3.5L codes P0037 P0507 One is a heat O2 sensor how can you know which one exactly


P0037 HO2S Heater Control Circuit Low (Bank 1 Sensor 2)
P0507 Idle Control System RPM Higher Than Expected
bank 1 is the side with number 1 spark plug but the o2 sensor is going to be the one just before the catalytic convertor. the other codes has to with idle and you either have a vacuum leak (which would cause eratic idle(up/down))or you have no accelerator cable and there is a problem with one of the sensors either at the throttle body or on the pedal assembly.
