The check engine light produced codes p1150 and p1155 on a 2000 toyota avalon xls.


All cars sold in the US after 1995 use the same on board diagnotics called OBD-II. The codes are the same. Search OBM-II error codes and you'll get a listing.

P1150 Air/Fuel Sensor Circuit Range/Performance. (cylinder bank 1 Sensor 2)

P1150 may mean that one or more of the following has happened:
water or corrosion in the O2 sensor connector, loose terminals in the connector, wiring burnt on exhaust components, open or short in the wiring due to rubbing on engine components, holes in exhaust allowing unmetered oxygen into exhaust system, unmetered vacuum leak at the engine, bad O2 sensor or bad PCM.

P1155 Air/Fuel Sensor Heater Circuit. (cylinder bank 1 Sensor 2)
P1155 may mean that one or more of the following has happened: O2 Heater element resistance is high, Internal short or open in the heater element or O2 heater circuit wiring high resistance

Solution :Replace oxygen sensor and see if the problem goes away.

The upper sensors are air fuel sensors and the lower ones are o2 sensors. you cant mix these up. Assuming you did everything right and still coding then either the new sensor b1s2 is bad or the wirng(power and ground need to be checked. A scan tool can be used to look at the performance of the sensors too. Sometimes the codes just point to the area of the problem and changing the part isn't the answer.

Oxygen sensor 2000 galant


Try replacing the gas tank cover. Seriously. If that does not work, it could be the clutch sensor.
