Very sorry! It’s a check engine light code off a 380-CE-D VOLVO PENTA on a 2014 Cobalt 336. Thanks!have a better chance of success if you give us an idea of which engine you have...
Yes it’s a check engine code PID: 15MID: 128 - Engine
PID: 15 - ??? are you sure it's 15?
FMI: 5 - typically low signal or open circuit

Did you ever find out what this code was? I just went on a Sea Trial for a boat I'm looking to buy and got the same code. It was not overheating but the coolant did get frothy.MID: 128 PSID: 15 FMI: 5
can anyone decode this please?
Thanks Mark. The mechanic is saying that no code is stored in the system. Would really like to know what it is/was before I finalize everything.I have searched high and low for Volvo PSID information and haven't had much luck. The "P" stands for Proprietary. I have found other information on Volvo EFI systems but nothing specific to this code. The only way that I know of is to pull codes with a Rinda TechMate Pro scan tool or their Diacom PC software.

Very informative......good to know. I was on the hunt for EVC manuals for curiosity's sake but no luck.The J1587 protocol (MID/PID/FMI) is used when the fault is in the EVC system. Sometimes there will be a crossover list in the EGC Diagnostics Workshop Manual for your engine. This will allow you to convert to a DTC that might be covered in that manual, but sometimes you will need a copy of the EVC manual for your version. You need to know what version of EVC you have. Sometimes you will need to use a VODIA scan tool. I have found that Diacom can fall short when working on EVC.
I have a 2021 VP 350 CE with the identical fault code. Thanks for sharing. BTW where did you find the info? My dealer can't find PSID 15.Ok, I figured it out…128 is engine, 15 has to do with O2 sensors, 5 is low voltage or signal problem.
I replaced all 4 O2 sensors…two up stream and two down stream. Turned out to be one of the down stream sensors was defective at the tip ( sensor tip). The upstream and downstream are different part numbers and expensive from Volvo as all their parts are. I found them on eBay for way less. NO MORE CHECK ENGINE LIGHT!!
