Hi,

My engine management light is on and error P1152 (Bank 1 Sensor 2) is showing. I have changed the sensor and cleared the codes but it's still happening.

I have even put the old sensor into Bank 2 (this was thought to be faulty) but the fault is still showing as Bank 1 Sensor 2.

I am now suspecting that the fault is on the wiring to the sensor plug but does anyone have any idea how to check this?

Thanks,
Tony

Guessing you have a recent RAV seeing as ye live in Nottingham. Might be helpful for others if you post up details of your cars age; mileage; series; colour; diesel or petrol; otherwise we'll be guessing its Robin Hoods carriage. By the way, is it green???

It's a 2001, 2.0 petrol, 77,000 miles. And yes it's green!!!

P1152 is not listed on my Toyota list (ie codes starting with 1) but I thought they were the same as the generic codes. P0152 is Bank 2 Sensor 1(not B1S2?) High volts. Makes a change from heater circuit failures such as my two.

Sorry, fault is P1155 (Bank 1, Sensor 2).

Any suggestions?

Wouldn't be my area but Googled [url="http://wiki.answers.com/Q/How_do_you_fix_P1155_error_code_AF_Ratio_sensor_in_a_Toyota_RAV4_2003"]this[/url]

Then that is still Bank 2 Sensor 1 and is the heater circuit. They usually go o/c after about 5 years. I believe they should be about 15 ohms.
