Showing matches for "Audi TT".
P0121: Throttle / pedal position sensor range / performance
The ECU sees a throttle or accelerator-position signal that is outside the expected relationship.
P2135: Throttle position sensor correlation
The redundant throttle-position signals disagree beyond the permitted tolerance.
P0068: Throttle body airflow correlation
Throttle position, manifold pressure, and measured airflow do not agree with one another.
P0011: Intake camshaft timing over-advanced, bank 1
The intake camshaft is more advanced than the ECU expects for the current operating condition.
P0014: Exhaust camshaft timing over-advanced, bank 1
The exhaust camshaft position is more advanced than commanded or is slow to return to the expected position.
P0016: Crankshaft / camshaft timing correlation
The ECU sees the crankshaft and camshaft signals outside their expected relationship.
P0017: Crankshaft / camshaft timing correlation, bank 1 sensor B
The exhaust-camshaft and crankshaft signals on bank 1 are outside their expected relationship.
P0046: Turbocharger boost-control circuit range / performance
Turbo actuator or boost-control response is outside the range expected by the ECU.
P0141: Oxygen sensor heater circuit, bank 1 sensor 2
The downstream oxygen sensor heater circuit is not reaching expected operation.
P0420: Catalyst efficiency below threshold, bank 1
Upstream and downstream oxygen-sensor behavior suggests insufficient catalyst oxygen-storage performance.
P0507: Idle control system RPM higher than expected
Idle speed is higher than the ECU's target after it has reached the limit of normal control correction.
P0562: System voltage low
System voltage fell below the level expected by the ECU during operation.
P0603: Internal control module keep-alive memory error
The engine controller has lost or detected corruption in memory retained when the ignition is off.
P0641: Sensor reference voltage A circuit open
A shared 5-volt reference circuit for engine sensors is missing, shorted, or pulled out of range.
P1101: Intake airflow system performance
Measured intake airflow does not match the ECU model across the expected operating range.
P2563: Turbocharger boost-control position sensor range / performance
The reported turbo actuator position does not match the requested or mechanically possible range.
U0100: Lost communication with engine control module
One or more modules stopped receiving expected messages from the engine controller.
U0121: Lost communication with ABS control module
Modules on the vehicle network are not receiving expected messages from the ABS or stability-control controller.
U0140: Lost communication with body control module
One or more modules have lost communication with the body control module.
U0401: Invalid data received from engine control module
Another control module has received implausible or corrupted information from the engine controller.
P0106: Manifold absolute pressure range / performance
The MAP sensor signal does not match the pressure expected from throttle position, boost, engine speed, and airflow.
P0234: Turbocharger overboost condition
Boost pressure exceeded the ECU's permitted target for the operating condition.
P0300: Random / multiple-cylinder misfire
Misfires are occurring across more than one cylinder or without one consistent cylinder pattern.
