What is the absolute pressure of the intake manifold?
The MAP sensor measures the absolute pressure inside the intake manifold of the engine. At sea level, atmospheric pressure is about 14.7 psi (pounds per square inch). When the engine is off, the absolute pressure inside the intake equals atmospheric pressure, so the MAP will indicate about 14.7 psi.
What does vacuum mean on an intake manifold?
At a perfect vacuum, the MAP sensor will read 0 psi. When the engine is running, the downward motion of the pistons create a vacuum inside the intake manifold (For the purposes of engine control, when a technician says vacuum, what they are really saying is pressure that is less than atmospheric pressure).

What is the OBD code for intake manifold runner?
All our repairs are backed by our 12-month / 12,000-mile warranty. P2015 is a generic OBD2 diagnostic trouble code point at a malfunction with the intake manifold runner position circuit. This code is similar to P2005, P2006, P2007, P2008, P2009, P2010 and P2013.
What does the p2015 code on an intake manifold mean?
What the P2015 code means. When this occurs, the ECU detects the out of range performance as it is looking for a specific values and when they are not seen the DTC P2015 is set. This causes a failsafe mode to be enabled which will remain till normal operation is found or the code is repaired.
When do you change the manifold runner sensor?
Then a scan tool will be used to monitor the manifold runner position sensor readings while the runner position is changed. Mistakes are commonly made when steps are not completed in the order they are in or when components are not diagnosed before they are replaced just because it is the most likely cause.
