P2153
Fuel Injector Group C Supply Voltage Circuit Low
Fuel injector circuit
Generic OBD-II
Medium
What it means
P2153 means the supply voltage feeding fuel-injector group C is lower than expected. If that voltage drops far enough, the injectors in that group can't open properly, causing misfires, rough running, and in the worst case stalling. The usual causes are wiring and connector faults, a blown feed fuse/relay, or a failing injector control module.
Medium
Can I keep driving? Drivable in many cases, but low supply voltage can stop a group of injectors from firing — expect misfires and possible stalling, so limit driving.
Common symptoms
What you'll notice
- Check-engine light on
- Misfire, rough running, or hesitation
- Loss of power on the affected injector group
- Possible hard start or stalling if the injectors stop firing
Common causes
Most likely first
- Open, shorted, or high-resistance wiring in the group C injector supply circuitLikely
- Poor connection or corrosion at the injector or module connectorCommon
- Blown fuse or failed relay feeding the injector groupCommon
- Faulty fuel injector control module (FICM) / driverLess often
- Rarely, a faulty ECM/PCMLess often
How to diagnose & fix
Work through it in order
- Read freeze-frame data and note which cylinders belong to group C.
- Inspect the injector group C supply wiring and connectors for opens, shorts, and corrosion.
- Check the feed fuse/relay and confirm battery voltage reaches the injector supply.
- Test the control module grounds against battery ground for a clean, low-resistance path.
- If supply and grounds are good, suspect the injector control module; replace and retest.
FAQ
Quick answers
Is it safe to drive with P2153?+
Drive as little as possible. If the affected injectors quit firing you'll get misfires and possible stalling, and raw fuel can harm the catalytic converter.
Can I just clear P2153?+
It returns quickly until the low-voltage supply circuit or module is repaired.
