P0139 AUDI code

What the P0139 code means. P0139 is the OBD-II generic code indicating that the O2 sensor for bank 1 sensor 2 failed to have a voltage drop below . 2 volts for 7 seconds during a deceleration fuel cut off. This failure shows that the engine control module (ECM) has determined the sensor response is […]

Replacing or reprogramming a defective TCM. Replacing wiring and/or connectors for a damaged transmission control circuit. What causes P0731? Code P0731 When the code P0731 is set […]

P1404 AUDI code

OBD II fault code P1404 is a manufacturer specific code that is defined by General Motors (Chevrolet in particular) as “Exhaust Gas Recirculation (EGR) Closed Position Performance”, and is set when the actual position of the EGR valve pintle does no coincide with the position of the EGR valve pintle the PCM (Powertrain … How […]

P0270 AUDI code

What the P0270 code means. This diagnostic trouble code indicates that the powertrain control module has detected a lower reference voltage from the fuel injector on the number 4 cylinder than what was specified by the vehicle manufacturer. What is code P0270? OBD-II Code P0270 is defined as a Cylinder 4 Injector Circuit Low. The […]

P0348 AUDI code

What the P0348 code means. This code tells the PCM that the camshaft position is incorrect for the optimal performance of the vehicle. If the camshaft sensor detects a voltage reading that is more than 10% higher than the manufacturer’s specifications, the P0348 code will be stored. What is code P0348 mean? OBD-II Code P0348 […]

P202B AUDI code

A stored code P202B means that the powertrain control module (PCM) has detected insufficient voltage in the control circuit for the reductant tank heater. The catalyst system is responsible for reduction of (basically) all exhaust emissions although certain applications are also equipped with a NOx trap. What does P202B code mean? Reductant Tank Heater Control […]

P025C AUDI code

What is fuel pump control module? The Fuel Pump Driver Module controls the voltage delivered to a vehicle’s fuel pump. By controlling the voltage, the module maintains optimal fuel pressure and fuel delivery to the engine throughout its full operating range. What does code P023F mean? Fuel Pump Secondary Circuit/Open P023F OBD-II: Fuel Pump Secondary […]

P0096 AUDI code

What the P0096 code means. P0096 is the OBD-II generic code indicating that the engine control module (ECM) has determined that the intake air temperature sensor 2 (IAT2) is not operating in the normal sensor range and the ECM cannot use the sensor output to determine intake air temperature. What is intake air temperature sensor? […]

P0294 AUDI code

Trouble code P0294 means that the number 12 cylinder in the firing order is experiencing either reduced or non-existent fuel delivery. If the PCM gets the signal that there is a lean mixture in one of the cylinders, it automatically sends a message to the other cylinders telling them to deliver a richer fuel mixture. […]

P0238 AUDI code

Code P0238 is triggered when the intake boost sensor circuit shorts to power or opens completely, causing the signal to the ECM to go way over, or below voltage specifications. The most common failure is the boost sensor shorted internally, or the harness has been shorted on the exhaust manifold. Where is the boost pressure […]
