Map Sensor Specs / Information?

johnpaul76 · 07-02-2009, 11:21 PM

Hi,

Does anyone have information (datasheet would be great) on the output from the map sensor on a JDM V7 engine? Is it a 3.5bar, 5 bar or something else?

The Subaru part number is 22627AA170, Denso pn is 079800-5320. The service manual says that its a straight line to its max, but doesn't say what max is. I'd liked to hook it to a datalogger, so looking for the voltage to psi (bar, etc) conversion.

Thanks.

The part number you listed is the same part number as the USDM 02-05 WRX.
It is a 2.5 bar map sensor.
Multiplier 9.943
Offset -8.005
