Yes, if it is clogged.
Crawl under the vehicle and look up at the exhaust system. The catalytic converter is the first part that looks like a muffler mounted in the exhaust system coming rearward from the engine.
Bank 1 is the passenger side of the engine in your E-150 Sensor 1 is between the engine and the catalytic converter ( upstream sensor )
I have a 1990 e150 and it has 2.
i am thinking there is 4 one at the exhuast manifold, one before the converter one after and one inline. some have only 2 one after the manifold and in line.. v6 and v8 may have 2 af the exhuast collectors and 2 before the catalytic converter 2 after the catalytic converter and one inline. all depends one the engine and where it was built and if it is a cali van or not..
Left front, right front, left rear, right rear, 4 converters total..
On a 2002 Ford E-150 : Bank 1 is the passenger side of the engine ( V6 and V8 engines ) Sensor 1 would be close to the engine BEFORE the exhaust enters the catalytic converter ( upstream sensor )
Right next to oil filler tube on the left (facing engine) but further back in engine compartment.
On 2000 & 2002 E150's there are 2 back-to-back converters on each side.
just take the big engine cover inside the veh, and the whole engine will come to your eyes.
how do you get the air out of the aux heater lines on a 1993 E-150 ford club wagon with 5.8 engine?
Where is the engine oil cooler on a 1998 Ford Econoline van E150
