The P0288: Cylinder 10 Injector Circuit Low indicates a problem with the electrical circuit controlling the fuel injector for cylinder 10. This issue could be due to a faulty injector, an open or shorted circuit in the wiring, or a malfunction in the injector driver within the ECM. When this code appears, it can cause misfires, poor engine performance, and higher emissions.
P0288 – Quick Overview
| Meaning | P0288: Cylinder 10 Injector Circuit Low |
| Is it serious? | Yes, this code is serious as it can cause poor engine performance, misfires, and increased emissions if not fixed promptly. |
| Possible causes | – Faulty cylinder 10 injector – Open or shorted circuit in the wiring – Faulty injector driver in the ECM |
| How to diagnose? | – Check the wiring and connectors for the cylinder 10 injector – Test the cylinder 10 injector for proper resistance – Inspect and test the ECM for fault codes related to injector driver |
P0288 Meaning
The P0288: Cylinder 10 Injector Circuit Low code means that the signal going to the fuel injector for cylinder 10 is lower than expected. This could result from an open or shorted wiring circuit, a malfunctioning injector, or a problem with the ECM’s injector driver. When this occurs, cylinder 10 may not receive the appropriate fuel, which can lead to rough idling, misfires, or reduced fuel efficiency.
