Test location for the inlet manifold pressure
Use the following procedure in order to measure the inlet manifold pressure:
Remove the inlet manifold pressure sensor from the cylinder head.
Install a T fitting into the port at the cylinder head.
Install the pressure sensor into one side of the T fitting.
Connect the 1U-5470 Engine Pressure Group into the other side of the T fitting. Note: In order for the engine to operate normally, the pressure sensor must be reinstalled onto the engine at this location.
Measure the inlet manifold pressure under similar engine conditions that are given in TMI. Record the value.
Compare the value that was recorded in Step 5 to the pressure that is given in the TMI.
