SOURCE: code 1507 idle air control

This code is saying that the engine speed is below spec, the idle air control motor controls the engine speed, if the speed was higher then you may have a few problems but since it was lower the only problems i've dealt with in this case is the valve is bad and also clean the throtle body, this valve is located on the throtlebody, hope this helps, also heres a picture of the valve to help you locate it.c6f5023.jpg

SOURCE: 91 mazda 626 erractic idle surge when engine is cold

My '91 626 did the same thing. I tested the throttle position sensor, and it was good so that wasn't it. The other likely culprit is the Idle Speed Control valve, or Idle Air Control valve, which is a $500 part new (more than I paid for the whole car). I pulled one off a 626 at the salvage yard and got it for 3 bucks, put it on (it's an easy DIY, just 4 philips screws holding it to the intake manifold), however I can't be sure that solved the problem, since I haven't run the car much since then. It would seem the most likely cause, tho, and a cheap fix if you go used. Other possibilities: O2 sensor or Mass Air Flow sensor?

SOURCE: P1131 manufacturer control fuel air metering. What

Hi Galant5Rov,

Firstly, congratulations to you on identifying the Trouble Code. This code relates to the Heated Oxygen Sensor (H02s)

The oxygen sensors supply the computer with a signal that indicates a rich or lean condition during engine operation (i.e. fuel/air metering).

This input information assists the computer in determining the proper air/fuel ratio. A low voltage signal from one or more sensors indicates too much oxygen in the exhaust (lean condition) and, conversely, a high voltage signal indicates too little oxygen in the exhaust (rich condition).

The oxygen sensors are threaded into the exhaust manifold and/or exhaust pipes on all vehicles.

A faulty oxygen sensor due to loose connections, bad grounds, high resistance in the circuit, or opens in the circuit can cause the following symptoms.
Related Symptoms

  • Surging at idle
  • Unstable idle
  • Running rough off idle
  • Hesitation
  • Stumble
  • Chuggle
  • Poor fuel economy
  • Spark knock
  • Stalling on acceleration
You must take EXTREME care when removing these sensors, as they can be difficult to remove (seize up). You may require a special tool to remove these without causing damage to the sensor.

Cheers,


"If this has helped you in any way, please rate this solution" :-)

P1507 code


P1507 means "Idle Air Control Underspeed Error". It can be most commonly caused by a vacuum leak, a damaged Idle Air Control (IAC) assembly or a stuck IAC valve that needs cleaning. Essentially, your engine isn't idling at high enough according to your computer's programming parameters. Many times this shows up in colder weather as you try and start your vehicle. It will usually die unless you put your foot on the gas pedal and raise the RPM's. I have also read where a clogged air filter might be the problem. I would try cleaning your IAC valve first.

Engine light code P1507: ''manf cntrl veh spd idle speed control auxiliary inputs'' and P0306: ''cylinder 6 misfire detected''. this ranger resitates press gas. where do i start?


P1507 is "Idle Air Control System Underspeed Error". This code indicates a problem with the Idle Air Control (IAC) valve assembly, harness wiring for the IAC or the Powertrain Control Module. So checking the IAC next is the most logical step.
