Oxygen Sensor

[Jans03]

I want to replace both O2 sensors in an 03 corolla.

The front one in the manifold with Bosch 13544 Oxygen Sensor
Bosch 13544 Oxygen Sensor ???




the rear one after the catalytic with ???
anyone have a part number for that one ?
BOSCH 15290 Oxygen Sensor ???



additionally, the guy at autozone said "you need a special tool to reset the codes afterwards"

so this is a two part question

1. what are the part numbers for the sensors ?
2. how do I reset the computer codes ?

thanks.

Welcome to the Corolla Forum!

First off, why do you want to replace them?

 

[Jans03]

check engine light
high miles.....etc. codes.... etc


how do I reset the computer codes ?

i already got the sensors with the part numbers above

I think you'd be best off using Toyota, or NGK o2 sensors and not German/Bosch o2 sensors in a Japanese manufactured vehicle.

The trouble codes indicate an o2 sensor problem?

The onboard computer is reset with a scanner, like this one -

so you are saying that you need a scanner to reset stored codes ?
and that unplugging the battery will not remove stored codes ?

these Bosch sensors are made in the USA
they are made to OEM specs
Bosch has excellent products,
and im pretty sure many toyotas were built in the USA as well.

 

[Scott O'Kashan]

Correct.

What were the trouble codes that indicated an o2 sensor problem?

Bosch has very good products, for German cars. It has been my thirty year automotive industry experience that it's usually best to use parts specifically designed for that car by the manufacturer, especially when it comes to ignition parts, (spark plugs), and sensors, like 02 sensors.

Ya I'm sure its an intake gasket issue instead of oxygen sensors. What code you getting like Scott said?

No, that's an O2 sensor code, had the same problems and it was o2s.

Check with Olathe, they are an OEM dealer but I always find the parts here for the same price as autozone stuff

I just bought O2s from them for cheap.
