What does the exhaust back pressure sensor do?
The MAP sensor measures pressure between the compressor wheel of the turbo and the intake of the engine, and the EBP measures pressure between the exhaust of the engine and the turbine wheel (exhaust side) of the turbo.
Can you clean exhaust back pressure sensor?
Hi, usually you can just scrape out the carbon from fitting and inlet of sensors with a very small screw driver. The tube likes to clog up. Some clean these but it’s a pain and you can buy a new one for about$40. Don’t forget to check fitting that comes out of exhaust manifold.
How much back pressure is too much?
Even GM, probably the most outspoken carmaker regarding backpressure testing, suggests different readings throughout its carline. For most of its engines, GM recommends no more than 8.62 kPa (1.25 psi) at idle, and no more than 20.68 kPa (3 psi) at 2,000 rpm.
Can exhaust back pressure damage an engine?
Excessive backpressure in the exhaust system create excessive heat, lower engine power and fuel penalty in the engine cylinder, that may cause damage of the engine parts and poor performance [5 ].
Where is the exhaust back pressure sensor?
The EBP sensor is located in a confined space between the serpentine belt and high pressure oil pump (front of engine). The EBPS on the 7.3L Power Stroke is located near the front of the engine, just in front of the high pressure oil pump. You’ll need to remove the plastic engine cover in order to gain access.
What is back pressure in exhaust?
Definition. Engine exhaust back pressure is defined as the exhaust gas pressure that is produced by the engine to overcome the hydraulic resistance of the exhaust system in order to discharge the gases into the atmosphere.
Where does the exhaust pressure sensor go?
Usually, you’ll find the sensor bolted onto the side or bottom of the engine, or along the firewall in the back of the engine well.
