What P2153 means
P2153 reports the third shared injector supply shorted toward ground. GM's 2018 Duramax tables use it only for the 6.6 L V8, where bank 3 feeds injectors 6 and 7; the four-cylinder 2.8 L has just two banks and never sets it. The criterion matches the other low codes – 0.5 Ω or less between a high-side pin and ground while the driver is on, 5 of 10 samples at 100 ms, type A. Ford lists group C among the injector driver checks of its 2023 diesels and flags shorts to ground or battery after about 0.2 s. On GM gasoline direct injection, shown in the Saab 9-5 2.0T procedure, P2153 means low voltage on the high-side control line of cylinder 3, set after 1 s, type B. Open circuit and high fault of this group are P2152 and P2154.

Common causes of P2153
- Most likelyGroup C supply wire chafed and shorted to ground

What to do next
- Note P2153 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
