Why does my DTC p0507 have idle speed control?
Depending on year, make, and model, DTC P0507 may have number of causes. Here are some of the most common. ECU Update – Newer vehicles, particularly those with drive-by-wire electronically-controlled throttle bodies, may not be equipped with an individual IAC, but use the main throttle valve to maintain idle speed.
What are the symptoms of code p0507?
Defective PCV Valve – If the PCV (positive crankcase ventilation) valve is stuck open, it will apply manifold vacuum to the crankcase, which may start sucking in air almost anywhere, such as from the dipstick tube or valve cover gasket. What are the symptoms of code P0507 ?
What does it take to clear a p0456 code?
For clearing codes and resetting lights, it normally needs a full “drive cycle”. Which means the car reaches normal operating temp, then is shut off, and goes full cold. Then the next cycle starts. Especially for an evap leak.

Why is my cold therapy unit not working?
4) Poor performance is often the result of a plugged filter. The filter is located at the tip of the pump on the inside of the CTU lid. It usually unscrews and can be rinsed under water. 5) The pad is designed to maintain a temperature of 45-55 degrees.
What does code p0507 mean on IAC system?
If you are having a problem with the IAC system, and the MIL is on, you may also notice the engine idling unusually high, or erratically idling high and low. You may also experience hard engine starting. How do you troubleshoot code P0507 ?
What does the idle-up valve on a PSP do?
PSP Idle-Up Valve – Many power steering systems include an idle-up VSV. When power steering pressure is detected by the valve, it opens a by-pass, allowing more air past the throttle body and increasing idle speed a couple hundred rpm. A broken valve may simply let air through all the time.
What causes an idle speed control system problem?
The following idle control system problems would most-likely be accompanied by fuel system lean codes, which should help in narrowing down your diagnosis. Vacuum Leak – Over time, rubber hoses tend to become brittle, especially in the heat of the engine compartment.
What does the DTC code p0504 mean?
Diagnostic Trouble Code (DTC): P0504 P0504 code definition. When a malfunction is detected in the brake light switch of a vehicle, the PCM (powertrain control module) records the P0504 code, and the Check Engine Light is illuminated. What the P0504 code means. If a failure occurs in the circuit for the brake light, a number of problems can occur.
What does the idle control system code p0505 mean?
Idle Control System Malfunction What the P0505 code means P0505 is an OBD-II generic code that the engine control module (ECM) determined the engine idle control system is not managing the idle to stay in specification. The idle is too high or goes too low.
What are the symptoms of the p0505 OBD-II trouble code?
What are the symptoms of the P0505 code? The Check Engine Light will be illuminated and the code is set in ECM memory. The engine idle may be lower or higher than specifications. The engine may idle rough if it has a vacuum leak. The engine may stall when coming to a stop. The engine may idle too high at times.
Why does my car have a p0504 brake light code?
Your vehicle’s powertrain control module (PCM) has set this P0504 code in response to a recognized failure in the brake light circuit. The vehicle’s computer monitors all circuits for abnormalities such as lack of voltage or an out of range condition.
