What is P0507?
P0507 indicates your engine's idle control system is running at higher RPMs than expected, which is a powertrain issue of medium severity. This typically occurs when the engine computer cannot properly regulate idle speed, often due to vacuum leaks or sensor problems. Based on real owner data, this code appears frequently in Honda Accord, Nissan Maxima, and Jeep Liberty models.
Common Causes:
- Vacuum leaks in the intake system (commonly mentioned in repair discussions)
- Faulty idle air control valve (IACV) or throttle body issues
- Dirty or malfunctioning mass airflow sensor (MAF)
Symptoms:
- Engine idling at higher RPM than normal (most common symptom)
- Check engine light illuminated with possible drivability issues
- Vehicle shuddering or rough operation at idle (reported in CR-V cases)

Real experiences from 2010 HONDA Accord owners
“I drove it 50-70 miles or so before I got the first P0507 after thinking I fixed the issue. I've changed the IACV again thinking maybe it was a dud, no luck.”View original
“I changed the IACV, and eventually got the idle down, after a couple attempts at an idle relearn via the procedure in the Haynes manual. I drove it 50-70 miles or so before I got the first P0507 after thinking I fixed the issue.”View original
“Looked for vacuum leaks but didn’t spot any. I’m thinking the throttle position sensor (TPS) or ECU needs a reset, but I don’t have a fancy 2-way OBD2 scanner .”View original
“She started by herself (yay, the battery got enough charge!), bu the problem still existed. Drove back the same distance on the highway, again no probs on the highway, I tried to pull codes while my friend was driving her and there were no codes.”View original
“Car Won’t Slow Down + P0507 Code After Throttle Body Cleaning I cleaned my throttle body to keep my Accord running smooth, but now I’m stuck with a P0507 code (Idle Control System RPM Higher Than Expected).”View original
“Obviously this is a DBW throttle body. Oh and to add, I have the infamous oil consumption issue and am currently treating with MMO every oil change till noticeable change.”View original
“I haven't started this car in 6 weeks, I went to start it a week ago and the battery was dead. Called a friend over this weekend and got a boost, she started right up.”View original
“Using a Foxwell NT510 Elite, I then reset the TPS to relearn and the rpm immediately went to normal range (700-800). Everything seems normal and has continued to for a month, cool.”View original
“I removed the throttle body for cleaning, and touched the throttle plate, and this could be causing my P0507 error. The only other thing I can think of is that the cleaning fluid sent carbon down into a throttle body passage and now is causing the error.”View original
“However, I note that the radio presets remain in place after doing this so I am not convinced that the ECM is being reset or not. I need to reset the ECM so that I can get the idle learn procedure completed from the SM for my electronic throttle body(integrated IACV) error (P0507) corrected.”View original
