there is a fuse for the o2 heaters if one of the sensors blew the fuse they will all be out

SOURCE: Error P0155

That code will not affect the drivability of the vehicle. The heater does just that: it heats up the oxygen sensor to operating temperature. You can change it yourself, raise the vehicle up, the sensor is the one on the passenger side, right after the exhaust manifold.

Thanks for choosing FixYa for advice!

I would check the O2 sensor, and if it checks bad, replace it, and clear the trouble codes. If the light comes back on, you may need to check further. .

My speedometer stop working what can i do to fix it


Causes...............

Faulty Vehicle Speed Sensor
- Vehicle speed sensor harness or connectors is open or shorted
- Vehicle speed sensor circuit poor electrical connection
- Faulty Engine Control Module (ECM)




The P0500 code is very common on the Toyota Tacoma, Toyota Yaris, Toyota Camry, Toyota Tundra, Toyota RAV-4. Before replacing the sensor you should try cleaning the sensor gear and erasing the code. If the light comes back you may have to replace the sensor.

You need to act now by next year this warranty will end since your vehicle will turn 10 years. The other thing is it got to be under 150,000 miles on it.

P1155 code for a toyota rav4 2002, engine lite came , took to parts store, put on diognostic machine , this code came up. wat does it mean?


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.

Hope helps (remember rated this).

Need to know where air-fuel sensor is on 2002 toyota rav 4


An air/fuel sensor is like an o2 sensor. It is in the exhaust system and looks just like an o2 sensor. You have 2 on the vehicle. We need the check engine light code to tell which one it is. Also recommend only Toyota's air/fuel sensor.
