First disconnect the battery and the reset switch is located just beneath the dashboard just above the throttle pedal. un-clip the casing via screws and open it and press the switch. Re fasten case and replace back into position. Reconnect the battery and you're set

Where are the O2 sensors located on a 1994 ford e350 van?


Hi Gerard,
The O2 sensor, also know as Lambda Sond, is screwed into the exhaust pipe.
You will find them just before, and just after the catalytic converter along the exhaust pipe.

Engine light is on and car is shaking


Hi,
Unless you take it to a shop to diagnose it, I would guess that it is due time to replace lambda sond,
The lamda sond is normally located a little down the exhaust manifold, maybe covered by a shield.
Good luck.

What is the function of lambda sond? it's good or bad ?it's about what?


First used in February of 1977 on Volvo B21 four cylinder engines, the Lambda-Sond system was an emissions reduction system which used three key components working together:-


1) Lambda Sensor. An exhaust gas composition sensor to monitor chemical composition of engine exhaust gases; especially NOx (oxides of nitrogen) which feeds data to the engine control system. In simple terms it's an oxygen sensor positioned in the exhaust pipe before the catalytic converter.


2) A feedback loop providing information to the engine control computer that enabled more precise control of the fuel injection system.


3) A catalytic converter.

This system greatly reduced exhaust emissions while allowing much better performance and fuel economy. It proved to be a key to restoring the performance lost by the addition of emission controls on vehicles. It was the forerunner to modern electronic engine management systems that eventually appeared as similar systems on all road-going vehicles.

So it's a very, very, good thing and like all similar systems requires periodic maintenance and repair, usually the parts which fail are the lambda sensor and/or the catalytic converter.

I hope that my speedy and free reply has met your requirements, if so then please take a brief moment to rate my answer.

What is a lawbda sensor on a 94 Audi 100 cs


All About Lambda Sensors The exhaust gas oxygen sensor (EGO or O2), or lambda sensor, is the key sensor in the engine fuel control feedback loop. The computer uses the O2 sensor’s input to balance the fuel mixture, leaning the mixture when the sensor reads rich and enriching the mixture when the sensor reads lean.
I pulled this off a web site for you, I didn't know what it was either till I saw your thing here. Hope this helps.

How do you check the O2 sensor


hi, the only way to really check the o2 sensor is buy removing it then running power through it but this can damage it further.
The most common thing you will notice if the lambda sensor (oxygen sensor) when the car starts from cold and if it runs ok when you run the car upto temperature if when its hot the engine doesnt run correc then this is usually proof the o2 sensor needs replacing.

What makes you think the o2 sensor is gone and are you going on about the lambda sensor in the exhaust if not then im sorry but let me know then i can assist you further ok

usualy if you can smell fuel while you crank it indicates that there is no spark or late spark, first i will check and make sure that the distributor rotor is ok and if it is the i assume the problem is in the timing belt, either it is broken or stripped either way the belt needs to be replaced
