If you’re experiencing an illuminated engine light and excessive fuel consumption, you may be dealing with the p2197 fault code.

  • The automobile fault code P2197 has two main symptoms.
  • The first symptom is that the engine light turns on.
  • The second symptom is that there is excessive fuel consumption.
  • It is important to note that these are the only two symptoms associated with this particular fault code.

P2197 fault code in automobiles can be caused by various factors, including faulty oxygen sensors, fuel pressure, and intake air leaks.

  • The automobile fault code P2197 can be caused by a faulty front heated oxygen sensor in bank 2.
  • It can also be caused by an open or shorted harness in the front heated oxygen sensor bank 2 circuit.
  • Poor electrical connection in the front heated oxygen sensor bank 2 circuit can also trigger the fault code.
  • Inappropriate fuel pressure, faulty fuel injectors, intake air leaks, and vacuum leaks can also be the causes of the P2197 fault code.

To fix the p2197 fault code, check the possible causes and inspect related wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code p2197, you need to check the possible causes listed above.
  • Visually inspect the related wiring harness and connectors.
  • Look for damaged components and check for broken, bent, pushed out, or corroded connector’s pins.
  • This fix will take an estimated repair time of 1.0 hour.

The fault code P2197 indicates a problem with the oxygen sensor in the engine’s air-fuel ratio. The estimated repair time for this fault code is 1.0 hour.

The cost of fixing this fault code varies between $75 and $150 per hour, depending on the auto repair shop.

The cost may also vary depending on the severity of the problem and the type of vehicle.

It is important to get this fault code diagnosed and fixed as soon as possible to avoid further damage to the engine and to ensure optimal performance of the vehicle.

The P2197 code is related to the oxygen sensor in the exhaust system.

The sensor detects oxygen levels and sends a signal to the Engine Control Module (ECM). The ECM uses this information to regulate the air-fuel ratio. The heated oxygen sensor generates output voltage between 0 V and 1.0 V in response to the oxygen concentration in exhaust gas.

If the heated oxygen sensor outputs a LEAN signal constantly, the ECM interprets this as a malfunction and sets a DTC. The P2197 code specifically indicates that the oxygen sensor signal is biased or stuck lean on Bank 2.

What are the possible causes of the P2197 automobile fault code?

If you notice the engine light on or service engine soon warning light, along with excessive fuel consumption, it could be due to the P2197 fault code. This code is caused by a faulty front heated oxygen sensor bank 2, open or shorted harness, poor electrical connection, inappropriate fuel pressure, faulty fuel injectors, intake air leaks, or vacuum leaks. To fix this issue, check the possible causes listed above, visually inspect the related wiring harness and connectors, and look for damaged components or corroded connector pins.
