2018年10月10日 · What Does P2197 Mean? The P2197 code is a result of the engine control module (ECM) indicating that the oxygen sensor is fluctuating outside its optimal range. This specified range is characterized by a minimum of 10 cycles per second.

Potential causes of a P2197 code include: Use a scan tool to get readings from the sensor, and monitor the short and long term fuel trim values and O2 sensor or Air Fuel Ratio sensor readings. Also, look at the freeze frame data to see the conditions at the time the code was set.

2024年12月10日 · What does the P2197 code mean? The P2197 code indicates a problem with the oxygen sensor signal. Specifically, it refers to Bank 2, Sensor 1. This sensor plays a critical role in monitoring the air-fuel mixture that your engine uses for combustion. When the P2197 code triggers, it means the O2 sensor is reporting that it’s stuck in a lean or ...

A P2197 code is caused by an ECM (Engine Control Module) receiving a signal that the oxygen sensor on is not working within the parameters set by the manufacturer. It’s job is to tell the engine control module when there is too much oxygen in the exhaust.

2020年6月14日 · What does the OBDII code P2197 on a Ford mean? - The code indicates that the oxygen sensor signal for Bank 2 Sensor 1 is biased or stuck lean, suggesting a potential issue with the sensor or the air-fuel mixture. 3. What are the possible causes of OBDII code P2197 in a …

2020年6月19日 · What does the P2197 OBDII code for a Toyota indicate? The P2197 code indicates that the oxygen sensor signal stuck lean for Bank 2 Sensor 1 in the exhaust system. 2. What are the common symptoms of a P2197 OBDII code in a Toyota? Common symptoms include poor fuel economy, rough idling, engine hesitation, …

2024年5月22日 · What Does P2197 Trouble Code Mean? The P2197 trouble code indicates that the oxygen sensor (O2 sensor) for Bank 2, Sensor 1 is detecting a lean condition for an extended period.

2017年3月31日 · What Does Code P2197 Mean? So, your OBD-II equipped vehicle has a stored code P2197? It simply means that the powertrain control module (PCM) has detected a signal from the upstream (or pre catalytic converter) oxygen (O2) sensor or circuit that is apparently stuck or improbable.

The BMW P2197 code is a diagnostic trouble code (DTC) that indicates an issue with the oxygen sensor signal in Bank 2 Sensor 1. Specifically, the code indicates that the O2 sensor signal is biased or stuck lean, meaning that it is not providing accurate readings to …

The P2197 fault code in automobiles indicates a problem with the Front Heated Oxygen Sensor Bank 2, which can cause the engine light to turn on and excessive fuel consumption. The cause of this issue can be a faulty sensor, open or shorted harness, poor electrical connection, inappropriate fuel pressure, faulty fuel injectors, or intake air or ...
