What are the possible causes of a p1155 Toyota?
P1155 TOYOTA Possible Causes 1 Faulty Air-Fuel Ratio (A/F) Sensor Bank 2 Sensor 1 2 Air-Fuel Ratio (A/F) Sensor Bank 2 Sensor 1 harness is open or shorted 3 Air-Fuel Ratio (A/F) Sensor Bank 2 Sensor 1 circuit poor electrical connection 4 Faulty Engine Control Module (ECM)
What does the OBD code p1155 stand for?
OBD-II code P1155 represents a malfunction in the air/fuel sensor heater circuit for bank 2, sensor 1. The air/fuel ratio sensor on your vehicle has to reach a particular operating temperature to produce accurate voltage signals.
What’s the proper operating temp for a p1155?
It needs to reach a minimum of 1200 degrees Fahrenheit before this can happen, and the sooner it reaches the operating range, the faster the sensor will be able to send accurate readings to the engine control module, or ECM. In order to reach the proper operating temp, there is a built in heater element as a part of the air/fuel ratio sensor.
What does the code p0125 on an OBD-II mean?
P0125 indicates1. bad Thermostat,2. low coolant level,3. bad coolant temperature sensor. Coolant level seems fine. Temperature gauage says, ok, in the middle. I replaced coolant temp. sensor. After 10- 15 minutes check engine light comes back on. In the past the O2 wires got cut.
What kind of check engine light is po125?
I reconnected them… My car developed with check engine light and faulty code was PO125, Toyota agents here replaced ECT sensor, 2 Oxygen sensors, but when I drove it naerly 10 kms, it came up again, Can you help me out to sort the issue….
What does p1155 mean on an oxygen sensor?
Oxygen sensors (Air fuel ratio sensors) are a common problem on many vehicles. A P1155 or P1135 code indicates you have a bad sensor. This is common in Toyota and Lexus cars and trucks.
What should the air fuel ratio sensor be at?
Air-Fuel Ratio (A/F)sensor need to reach a minimum operating temperature of 1200 degrees F to produce an accurate voltage signal. The faster the air-fuel ratio sensor reaches that temperature the faster the sensor will start sending an accurate signal to the Engine Control Module ( ECM ).
