Fuel Injector Group Supply Voltage Circuit Low
The P2153 code indicates that the powertrain control module (PCM) has detected a low voltage condition in the supply circuit for a group of fuel injectors. This can be caused by a faulty injector driver, wiring issues, or a failing PCM. The injector group may not operate correctly, leading to poor engine performance.
01. Most Common Causes
- Faulty fuel injector driver circuit
- Damaged wiring or connectors in the injector supply circuit
- Failed PCM (Powertrain Control Module)
02. Symptoms You Will Notice
- Engine misfire or rough idle
- Check Engine Light illuminated
- Reduced fuel economy
- Engine stalling or hesitation
03. Step-by-Step Diagnosis
Step 1: Use a scan tool to retrieve all codes and freeze frame data.
Step 2: Inspect wiring and connectors for damage, corrosion, or loose connections.
Step 3: Test voltage at the injector group supply circuit with a multimeter.
Step 4: Check the injector driver circuit for shorts or opens.
Step 5: If all else is fine, test the PCM for proper operation.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended to drive with this code as it can cause engine misfires, poor performance, and potential damage to the catalytic converter.
How much does it cost to fix?▼
The cost typically ranges from $50 to $150 for diagnosis and repair, but can be higher if the PCM needs replacement.
