a p0160c code
took it in for glow plug DTC and got it back with this code. shop said ECM was losing memory. Any thoughts??

P0160C
DTC P160C
DTC DESCRIPTOR DTC P160C Engine Calibration Information Not Programmed-GPCM DIAGNOSTIC FAULT INFORMATION Always perform the Diagnostic System Check - Vehicle prior to using this diagnostic procedure. See: Diagnostic Trouble Code Tests and Associated Procedures CIRCUIT/SYSTEM DESCRIPTION The control functions for the fuel injection system are integrated in the engine control module (ECM). During the manufacturing process, each injector's flow rate is measured and recorded as injection quantity adjustment (IQA) flow rate data. The flow rate data is then etched as a hexadecimal number on the body of the injector. This data, together with the injector's cylinder position, is stored in the memory of both the glow plug control module (GPCM) and the ECM. When the ignition is turn ON, both the GPCM and the ECM monitor to ensure that the fuel injection flow rate numbers are present. If any of the injector flow rate numbers are missing, the diagnostic for that control module will set the appropriate DTC. CONDITIONS FOR RUNNING THE DTC The ignition is ON. CONDITIONS FOR SETTING THE DTC The fuel injector IQA flow rate data is not programmed. ACTION TAKEN WHEN THE DTC SETS
Review the Display ECM & GPCM Inj. Flow Rates parameter with a scan tool. All cylinders should be programmed with a flow rate number. Both the GPCM and the ECM should be programmed with the same flow rate numbers for the corresponding cylinders.
Always perform the Diagnostic Repair Verification after completing the diagnostic procedure. |
Thanks!!!
After leaving shop and not being able to find anything on the code they told me I took it to the parts store to pull the code myself. And sure enough they told (even wrote down) me the wrong code. Im going to try and take it to a stealer to have the ECM flashed and see if that takes care of it. The shop had replaced one injector and the GPCM so I hope the reprogramming will take care of my MIL. Will let you know of the outcome!
