P062D
Fuel Injector Driver Circuit Performance Bank 1
Fuel injection / ECM driver
Generic OBD-II
High
What it means
P062D means the engine control module has detected a performance problem with its fuel-injector driver circuit for bank 1 — the internal driver that switches the injectors on that bank. It can lead to misfires, rough running, or reduced power on bank 1, and in some cases hard starting, though the engine often still runs.

Can I keep driving? Get it looked at promptly — a failing injector driver can cause misfires or rough running on bank 1 and, in some cases, a hard start; drive gently until it's repaired.
Common symptoms
What you'll notice
- Check-engine light on
- Rough running or misfire on bank 1

- Possible hard starting
Common causes
Most likely first
- Short to ground or an open in a bank-1 injector circuitLikely
- Shorted or failed fuel injector overloading the driverCommon
- Poor power or ground connections to the ECMCommon
- Internal ECM injector-driver failureLess often
How to diagnose & fix
Work through it in order
- Read freeze-frame data and check for cylinder-specific injector or misfire codes.
- Inspect bank-1 injector wiring and connectors for shorts to ground and opens.
- Measure each injector's resistance against spec and replace any that are shorted.
- Verify the ECM's power and ground circuits.
- Replace the ECM only if the internal driver has failed. Clear and re-test.
