If you have noticed a steady decline in MPGs, the first place you want to look is the Exhaust Back Pressure tube and sensor. Why here? Because its free and easy to fix if it is the problem, and quite often it is.

 

hey man great video. going to go clean mine right now..

 

Glad it helped!

 

hey man thanks again for the video. Made it a breeze. My exhaust back pressure sensor was so plugged up. looked like guide vanes or something. all went well used weed eater line for tubing and ran tubing throu parts washer. looking forward to the MPG increase.

 

Awesome! I'm getting great feedback from that video

I'm glad so many people found it helpful!
Let us know if you notice a MPG gain!

 

I want to say thanks for the support guys! I checked my online stats today, and I have gotten a HUGE response to this video.

Thanks guys, I love getting feedback from you guys!!

 

Just curious, but how does this help mileage? I thought this sensor was just a engine safety for when it saw too much exhaust pressure that the pcm would defuel the motor. Is there any actually monitoring going on and fuel adjustments based on pressure per rpm? Similar to a intake MAP sensor?

 

The EBPS (to the best of my knowledge) controls fuel mapping. Also, it controls the EBPV which works with the turbo to increase load on the motor. With a clogged EBPS the EBPV can be actuated all the time and put an increased load on the motor.

I am no expert, but you can ask the experts. Most people who own companies who produce tunes can shed some light on it.

According to Jody Tipton, DP Tuner: "a properly installed sensor in good working order is necessary for optimum PCM control of fueling."

 

it must have something to do with mileage. my EBPV goes nuts when it's cold and i have pretty bad mileage right now. the new sensor better come in soon.

 

The EBPS and the EBPV are not 100% the same. The EBPV will activate in the cold (I believe its triggered by the IAT sensor). This will cause extra load on the engine to make it warm up faster. The same effect happens when the EBPS is clogged, it will activate the EBPV, which has the same effect as cold temperatures.
