What is code p1055 2003 Toyota Highlander base model


The code 1055 is brand specific, and for Toyota it means there is a problem with the heater circuit for the O2 sensor bank 2 sensor 1. That is the sensor in front of the catalytic converter or split and on the side with cylinder number 2 which may be the passenger side.
The sensor could have failed, or it could be a problem with the power source for the heater inside the sensor.

Need to replace bank 2 sensor 2 on 2003 toyota highlander , where is it located


Bank 2, sensor 2 is a heated O2 sensor located below (after) the catalytic converter on the passenger-side. When this sensor gets clogged and/or goes bad from rust and heat fatigue, the voltage drops low enough to cause the electronic control module to register error code P0161, which then causes the check engine light to come on.

To replace Bank 2, sensor 2, remove the debri shield from just behind the front bumper, underneath the vehicle. There will be 10 bolts holding it on (10mm, I believe). After removing it, look toward the center of the newly exposed area and you will see 2 finger-like objects projecting out from the engine with wires coming out of each. The one on the left (passenger-side) is bank 2, sensor 2. The one on the right (driver-side) is bank 1, sensor 2.

I got my direct-fit sensor online for $55 from Remart Auto Parts. I know it is tempting to get the universal-fit type and save the cash. But after doing that once, I wouldn't care to do it again.

I found a YouTube video showing pictures of where the two lower (after catalytic converter) sensors are located. While the video only points out the driver-side sensor (bank 1, sensor 2), it's easy to spot the other one being only inches away.
