1999 Psd 4x4 Exhaust Backpressure Sensor Line Blockage

Anyone Know What Happens If The Exhaust Backpressure Sensor Is Blocked. It Looks Like Oil Or Carbon Buildup. What Does It Affect? And Whats The Easy Way To Clean The Line?

Thanks Chris

I used fencing wire, and carb cleaner, or brake cleaner... once i had it off. It will keep the Exhaust back pressure sensor from reading true. It can cause defueling as a result of measuring too high of back pressure.

you can get a sensor eliminator to put on there that will tell the computer it is working fine, so you won't have to clean it all the time.

Is this something that gets clogged/blocked easily? How hard is it to change and where is it located? I have put close to 100k on mine since I bought it (92K onit then) and never cleaned it; should I have been? This could be part of my mileage issue>>>>

its not hard at all to clean, but don't start on it unless your motor is cooled off! I just bought the sensor eliminator from dFuser, and let it go...
