How do you change oxygen sensor in 1992 Toyota corolla? Is there a model engine 4A-FE without a oxygen sensor?
The oxygen sensors on a 2004 Toyota Corolla are located within the exhaust manifold. They constantly monitor oxygen levels in the exhaust and allow the engine to make adjustments accordingly.
The 1985 Toyota Corolla has one.
under the hood
== == 1996 Corolla's have two oxygen sensors. The first sensor, is pre catalytic converter. It is located on the exhaust manifold. The second sensor is post catalytic converter.
on my car it was the front oxygen sensor. take the car to auto zone and they can put a computer tester on it and tell you what the problem is. they test it for free...
It screwed in to the exhaust manifold. To change it you unplug the sensor and unscrew it with an O2 sensor socket.
I think only 1. it's located below exhaust manifold before the cat converter.
A Toyota 5vz-fe engine has two oxygen sensors. There is a higher and lower sensor which send air and fuel readings to the ECU so the engine can run properly.
look at your exhaust header, which is on the left side of the engine (when looking towards the front of the car). it may have one wire attached, some cars have 4. It is approx 2 inches long, 1/2 diameter.
It depends on number of cylinders the engine has. 4 cylinder engine has 2 oxygen sensors. V6 has at least 3.
must be a oxygen sensor
