2005 Nissan Altima Error Code P0507
Contents |
What does that mean? 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 2003 nissan altima code p0507 to the engine. They rely on sensors and electronics to control the throttle. In

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. Potential

Symptoms Most likely you'll notice the idle speed is higher than normal. There are potentially other symptoms as well. Of course, when trouble codes are set, the MIL (malfunction indicator lamp, a.k.a. the check engine light) illuminates. Causes 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 p0507 nissan murano positive crankcase ventilation (PCV) valve Damaged/failed/dirty throttle body Failed EVAP system Failed IAC (idle air controller) or faulty IAC circuit Possible Solutions 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 procedures.

START 2004 Nissan Altima, P0507 Surging / High Idle Author SparkyPosted on August 21, 2011June 14, 2016Categories 2004, Altima, Altima, Find Answers, Nissan, P0507Tags Altima, Nissan, P0507 This 2004 Nissan Altima 2.5S came in with a high cold idle followed by a high and nissan altima surging warm idle. A few of the things I noticed right away was a fairly new battery. And a new starter assembly. I wanted to take a look at the throttle body, so I removed the intake tube by loosening the clamp at the Mass Air Flow sensor. Then the clamp at the throttle body. I had to disconnect the vent tube to the nissan altima code valve cover and this hose that is the transmission vent hose. It is very important that this hose be put back in place when the intake tube is reinstalled. I did not really want to see this. Notice the run marks left by throttle body cleaner being sprayed into the air horn. Also pay attention to the fact that some of the electronics are below the throttle plate. I do not have a Nissan Consult II scan tool so I needed to perform a manual relearn procedure for Idle Air Volume. After many hours of trying every conceivable variation of the relearn procedure I decided the throttle body had to be replaced. I wanted to document the relearn procedure step by step so I started again with the factory procedure as given by Mitchell. It did not work, so I modified it, to what did work for me. Along with some general clarification. This is quite lengthy so please bear with me. First of all, IF the battery, ECM or throttle body has been disconnected these conditions may all have to be performed to stabilize the idle and remove the
