Keep Your MAP Sensor Clean
Full Video Transcript
00:00 there is a problem with late model diesel engines that the oems won’t tell you about because it happens so slowly and if I have to replace another one of these sensors again I’m going to lose it this little guy right here is your map sensor also known as a manifold absolute
00:15 pressure sensor and this will send critical data to your truck’s ECM to calculate things like air fuel ratio and injection timing but there’s a problem this lives in your intake manifold which is at the mercy of your beloved EGR system meaning that Airstream is going
00:29 to be contam at with exhaust s and sticky oil Vapor that’s going to land on your sensor and end up clogging the hell out of it looking like this no it doesn’t happen overnight but it happens and that blockage is going to skew your readings and ultimately lower power
00:43 output and fuel economy so here at Banks we’ve engineered a map spacer kit and this spacer allows you to take that delicate sensor out of the contaminated flow stream and save you from having to replace this sensor every few th000 miles and we make them for late model

All modern Diesel engines have a Manifold Absolute Pressure (MAP) sensor. Your vehicle’s engine control module (ECM) relies on pressure data (and, in some cases, temperature) collected from this sensor to calculate the proper air-fuel ratio and injection timing.
Here’s the problem. The sensor sits in the middle of the oily, recirculated exhaust stream. As it gets caked in sticky oil and soot, its measurements become inaccurate, and you end up with reduced power and fuel economy. It doesn’t happen overnight, but it does happen.
The Banks MAP Spacer Relocation Kit is an attractive, easy way to prevent this oily soot from building on your MAP sensor by relocating it out of the contaminated exhaust stream. The sensor stays clean much longer, resulting in consistent power and fuel economy. The small billet devices can be installed in less than 10 minutes and are available for late-model GM, Ford, and RAM 6-liter Diesels.
