GM MAP Sensor Identification - quick reference

SYO237

SyTy Registry
Thanks to SBNova for showing me this info.

We all know we cant rely on telling if a MAP sensor is a 1, 2, or 3 Bar by the color of the insert (orange or black)

So, here is the breakdown of what the stamped numbers mean on your MAP. There are 7 digits on the topside of the sensor. The first 3 digits is the pin number to what Bar it is, the second set of 4 digits refers to the manufacturer date.

Pin numbers to what MAP you have:

1 Bar: 039, 460, 883
2 Bar: 886, 012, 539, 609
3 Bar: 749


The manufacturer date is decoded:

Example: 1125

So the sensor was made in 199"1" on the "125"th day of the year.
