Move That MAP Sensor! Diesel MAP Sensor Relocation Kit Upgrade

Modern diesel trucks rely on advanced sensors to operate at peak efficiency, and the Manifold Absolute Pressure (MAP) sensor plays a crucial role. A clean MAP sensor is vital for accurate intake manifold pressure readings, which directly affect your engine’s fuel injection and ignition timing.

However, your engine’s EGR (Exhaust Gas Recirculation) and PCV (Positive Crankcase Ventilation) systems constantly draw unburnt exhaust gases and oil vapor into the combustion chambers. While this lowers combustion temperatures and reduces emissions, it also causes thick soot to build up on the MAP sensor. This contamination leads to inaccurate ECU readings, severely hurting your fuel economy and power output.

0:00 here is a problem with late model
0:01 diesel engines that the oems won’t tell
0:03 you about because it happens so slowly
0:06 and if I have to replace another one of
0:08 these sensors again I’m going to lose it
0:10 this little guy right here is your map
0:12 sensor also known as a manifold absolute
0:15 pressure sensor and this will send
0:17 critical data to your truck’s ECM to
0:19 calculate things like air fuel ratio and
0:21 injection timing but there’s a problem
0:24 this lives in your intake manifold which
0:25 is at the mercy of your beloved EGR
0:27 system meaning that Airstream is going
0:29 to be contain lated with exhaust s and
0:31 sticky oil Vapor that’s going to land on
0:33 your sensor and end up clogging the hell
0:34 out of it looking like this no it
0:37 doesn’t happen overnight but it happens
0:39 and that blockage is going to skew your
0:41 readings and ultimately lower power
0:42 output and fuel economy so here at Banks
0:45 we’ve engineered a map spacer kit and
0:48 this spacer allows you to take that
0:49 delicate sensor out of the contaminated

0:54 replace this sensor every few thousand

Here 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 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 to be contaminated with exhaust soot 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 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 thousand miles, and we make them for late model Cummins, Power Strokes, and Duramaxes.

The Banks MAP Sensor Relocation Kit solves this problem by moving the sensor completely out of the dirty exhaust gas stream. These precision billet parts are easy to install with basic hand tools in just minutes. By getting your stock MAP sensor away from the oily flow, you ensure its reports to the ECU remain highly dependable. This simple upgrade guarantees constant power, better reliability, and improved MPG.

The Engineering Behind the Relocation

Relocating the sensor alters the localized fluid dynamics within the intake manifold. By withdrawing the sensitive electronic element from the direct path of dense, soot-laden EGR flow, the kit prevents particulate accumulation while maintaining perfect pressure sampling accuracy for the ECM.
