Hi,
First technical question so here goes
I'm getting some over boost at times and think I've narrowed it down to the Denso 079800-4110 MAP sensor.
These are the values I get measuring the voltages using a vaccum tool:
-14 psi = 1.68V
0 psi = 2.41V
5 psi = 2.79V
10 psi = 3.30V
20 psi = 4.40V (or close)
26 psi = 4.92V (max voltage)
Car is mapped for 1.5 bar
Sorry for the psi but that's the units of the tool.
Now these values head in one direction and maintain voltage at any given pressure, but should it not be exactly 0V - 5V?
Car is a V3 type-R so dont know if the Denso part listed above is correct (original) or available on any other cars so I could try a different unit.
Does any one else think the voltages are wrong or can perform a test also.
Any suitable replacement part that will not require a ruddy remap (not convenient at the moment).
I have tested the boost solenoid and that works fine, also the actuator works fine too!!
Sorry if formating is poor as using my phone to post.
Many thanks for any help.
