Cobalt L4-2.0L SC VIN P (2005)
Before following the diagnostic information in SI on DTCs P1516, P2135 and/or P2138, an inspection of the PCM serial number year and Julian (PCM
build) date will be necessary to determine if the PCM will need to be replaced to correct the repeat DTC P1516. Refer to Engine Control Module
Replacement in SI in order to remove the PCM. Refer to the above graphic illustration (1) for the location of the PCM serial number.
The serial number is read left to right. The last digit of the year is the 9th character and the Julian date is comprised of the 10th, 11th and 12th characters
and is used to determine the PCM build date. Refer to the example below to read a build date from the PCM serial number:
* 8 6 Y N AU K 1 5 3 2 5 0 R P N *
If the PCM year and Julian dates are between 5182 and 5304,replace the PCM. Refer to the Part Catalog to order the correct PCM for your vehicle
application, if necessary.
Vehicles with PCM built outside the dates should refer to SI diagnostics for DTCs P1516, P2135 and/or P2138.
