When is the p0507 idle air control system higher than expected?
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.
When to set the p0507 diagnostic trouble code?
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.
What does a p0505 code on a car mean?
For the driver, a P0505 code will usually mean that the engine becomes hard to start, runs roughly, or idles erratically. The engine may also shut off (choke out or stall) at stop lights after being driven to temperature (e.g. only after the vehicle has “warmed up”).
What are the symptoms of a bad EGR valve?
A rough idle upon starting the engine (that is, when the engine is cold) and sometimes at a stop light or while looking for a spot in a parking lot (that is, at low engine speeds in a warmed-up engine). Stalling when the engine idles. Increase in fuel consumption.

When to set the p2279 intake air system code?
When the mass airflow, the intake air temperature and oxygen sensor show a disparity a leak is recognized and the code P2279 is set. Air leaks at the air filter or hoses leading up to the mass airflow sensor (MAF) or throttle body are of no concern.
What does the oxygen sensor code p2279 mean?
The oxygen sensor is a tool used to confirm and maintain the fuel/air ratio. When the mass airflow, the intake air temperature and oxygen sensor show a disparity a leak is recognized and the code P2279 is set. Air leaks at the air filter or hoses leading up to the mass airflow sensor (MAF) or throttle body are of no concern.
What are the symptoms of a p2279 engine code?
Symptoms of a P2279 engine code may include. Malfunction Indicator Lamp (MIL) illumination with P2279 diagnostic trouble code set ECM sets additional codes such as engine miss in number 1 cylinder Cherry red exhaust manifolds from overly lean mixture Increased resistance in the power brakes (harder pedal)
What does the p0507 code on the ECM mean?
What Does P0507 Mean? The P0507 code is triggered when the Engine Control Module ( ECM) detects that the engine is idling higher than the specified idle rpm range. The standard engine idle is usually between 600-800rpm based on the model of the vehicle.
Is the p2279 air intake leak fault when towing?
Vehicle runs fine with no symptoms but throws P2279 air intake leak fault when towing. Fault clears with new ignition cycle and runs fine when solo. Landrover Assist and Servive centre have disconnected air intake to throttle body and checked all ok.
Can a aftermarket PCV valve cause idle problems?
If you see an aftermarket PCV valve, exchange it for an OE valve. Believe it or not, I’ve seen idle issues caused by aftermarket PCV valves on Honda’s. The OE PCV valves last just about forever so you can easily justify the expense. I will admit however that the OE valves sometimes come apart internally and cause idle problems.
How to check for DTC code p1077?
1. Reset the ECM/PCM. 2. Start the engine, and hold it at 3,000 RPM with no load (in park or neutral) until the radiator fan comes on. Is DTC P1077 indicated? YES – Go to step 3. NO – Intermittent failure, system is okay at this time. Check for poor (IMRC) solenoid valve and at the ECM/PCM. 3.
What causes the p0178 OBD-II trouble code?
P0178 is a generic OBD-II code indicating that the diesel fuel sensor is giving a low input, which could be from an open circuit in the sensor or wiring What causes the P0178 code? The engine control module (ECM) detects that the sensor circuit is open if the sensor input is below specifications
What does the OBD code p0509 mean?
This OBD-II code belongs to a series of fault codes (P0505 to P0509) that pertain to a fault in the idle control system, and it means that the engine computer has detected that the engine idle speed has exceeded the manufacturer’s pre-programmed specifications for a certain amount of time.
What is the code for idle speed control?
Hey Kev2: When AutoZone read me the code 0751 because I asked why my ETS light was on, I assumed they were related. Went back to AutoZone today and got more details. The P0751 is for the shift solenoid valve failure. They also found P0507 for the Idle Air Control (IAC) saying engine idle speed is… Hello All, I have a 1996 Chevy Lumina]
When does the idle control system code p0507 occur?
The P0507 trouble code is being triggered when the idle control system RPM is Higher than expected. All modern engines do have a desired idle rpm, usually between 600-1000 rpm.
What does the Thi p0507 code set mean?
Thi P0507 code sets when the Powertrain Control Module (PCM) detects an engine speed outside of the Idle Air Control (IAC) valve range of control. Possible symptoms. P0507 Chevrolet Description. The Idle Air Control (IAC) valve is a Powertrain Control Module (PCM) controlled stepper motor located on the throttle body.
