SOURCE: p0051 code, where is the sensor located, where is

Bank 2 is passenger side, sensor 1 is the one up closest to the exhaust manifold. Plug in type (just remove old and plug back into the wiring harness connector) is about $90 at Autozone. You can get a cheaper one that you splice but it's confusing to understand which wires to splice together. Don't forget to buy the special socket, $10, to remove and install the sensor. It's split up the side for the wires. Forget trying to use an open end wrench, socket is best.

SOURCE: need to replace bank 2 sensor 2 on 2003 toyota

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.

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.

I have a p1155 error code on a 2002 toyota highlander. what should i do?


P1155: Air/Fuel Ratio Sensor Heater Circuit Malfunction (Bank 1 Sensor 1) The sensor is on the Bank 1 throttle body with electrical connection. Its a delicate sensor. Unscrew it from the throttle body and check if its dirty, spray it with electronic cleaner with care. If its damaged, just replace it. If its not rectified, the car computer may default the air temperature to 20 degC and the air flow will not be correct and may have the following effect: 1. You might have difficulty in winter startups 2. Loss fuel efficiency (air/fuel ratio is messed up)/NOx problems/failed emission test/prematured catalytic converter replacement etc. CLARIFICATION An Air Fuel Ratio Sensor is also known as Wide Range Oxygen Sensor. Bank 1 Sensor 1 is mounted in the exhaust header before the Catalytic Converter (CC). The ECU uses the signal from the AF sensor to adjust Air/Fuel ratio. On V6 and V8 engines there is a second AF Sensor in the other header. (Bank 2 Sensor 1). After the CC there is a narrow range O2 sensor called Bank 1 Sensor 2. It monitors the CC. If there are two CCs there is a second O2 sensor (Bank 2 Sensor 2) The AF Sensor draws about 3 amps so check connections. The heater is a resistor between the B+ and HT terminals of the plug. On V engines there is also a AF relay to check.
