P039A Audi Rs5 OBD Code

OBD/2 P039A error code description and symptoms.

The Camshaft Position sensor will signal the Engine Control Module when the #1 cylinder is ready for the spark plug to fire (top-dead-center on compression stroke). The ECM uses the information from this sensor to help calculate fuel delivery and spark timing.

As the engine heats up and combustion becomes easier and more complete, the PCM will command the idling control valve to increase the amount of air entering the engine to suit the changing conditions. However, when the load on the engine changes, say, when some electrical consumers or other systems are either turned on or off, the PCM adapts the signal voltage to the idle control valve to ensure that the idling speed remains stable, and at the RPM specified by the manufacturer.

P039A Audi Rs5 Error Code Repair Process :

If your vehicle failed a P039A test and the P039A Check Engine Light is NOT on, chances are you have a problem with the OBDII system, a burned out MIL lamp, or a faulty catalytic converter. The converter is essentially an afterburner that cleans up the exhaust after it exits the engine. The OBDII system uses throttle position (tp) sensor circuit intermittent low voltage a ownstream oxygen sensor to monitor the efficiency of the converter, and it should detect a drop in converter efficiency if the converter has been contaminated or is failing (ignition misfiring, leaky exhaust valves, and oil burning can all damage the converter). What you want to look throttle position (tp) sensor circuit intermittent low voltage: Any conditions that might cause ignition misfire, an overly rich or lean fuel condition, or loss of compression. Use your OBD Express DIY to look at the oxygen sensor outputs, coolant temperature, airflow, calculated engine load, and inlet air temperature.

Common Causes of Audi Rs5 P039A OBD2 Code

A common cause of code P039A is the failure of Throttle Position (TP) Sensor Circuit Intermittent Low Voltage, but there are several other possible causes as well, such as ;

Clogged or faulty fuel injector (s)
Air fuel ratio (A/F) Sensor 1 Bank 1 harness is open or shorted
Damaged VCT phaser
Faulty oil control valve (OCV)

P039A is a kind of Powertrain Trouble Code

Powertrain of a modern automobile, comprising engine (with exhaust system), transmission, drive shaft, suspension and the wheels. In a motor vehicle, the term powertrain or powerplant describes the main components that generate power and deliver it to the road surface, water, or air.
