The P1155 code on a 2001 Toyota RAV4 indicates a problem with the air-fuel ratio sensor, specifically that the sensor signal is out of range or not functioning correctly. This sensor is responsible for monitoring the air-fuel mixture to optimize engine performance and emissions. Common causes for this code include a faulty sensor, wiring issues, or exhaust leaks. Addressing this code typically involves diagnosing the sensor and its related components to ensure proper operation.

The P1155 code on a 2002 Toyota RAV4 indicates a problem with the air-fuel ratio sensor (A/F sensor) in the engine. To fix it, first check the wiring and connectors for any damage or corrosion, as these can cause signal issues. If the wiring is intact, the sensor itself may need to be replaced. After replacing the sensor, clear the code from the vehicle's computer and take it for a test drive to ensure the issue is resolved.

The coolant temperature sensor on a 2001 Toyota RAV4 is located on the exhaust manifold. It is on the driver's side of the manifold.
Bank 2 sensor 1 Air fuel sensor heater circuit. This sensor is NOT an O2 sensor, though it operates like one and in the same location(in exhaust stream). Basically the PCM detected that the heater circuit was drawing excessive amperage or no amperage. Usually it's a bad a/f sensor and replacing it will fix it, however, it doesn't rule out the possibility of damaged wiring or an open in the power or ground circuit, or a short in the power or ground circuit.
