Cylinder 10 Injector Circuit Low
The P0288 code indicates that the powertrain control module (PCM) has detected a low voltage or resistance condition in the electrical circuit of the fuel injector for cylinder 10. This can be caused by a faulty injector, damaged wiring, poor electrical connections, or a problem with the PCM itself. The injector circuit is monitored for proper voltage and current; when the signal is lower than expected, the code is set.
01. Most Common Causes
- Faulty fuel injector on cylinder 10
- Open or shorted wiring in injector circuit
- Poor electrical connection at injector or PCM
- Failed PCM (rare)
02. Symptoms You Will Notice
- Engine misfire on cylinder 10
- Rough idle or hesitation
- Decreased fuel economy
- Check Engine Light illuminated
03. Step-by-Step Diagnosis
Step 1: Scan for codes and record freeze frame data.
Step 2: Visually inspect injector connector and wiring for damage or corrosion.
Step 3: Measure resistance of cylinder 10 injector; compare to spec (typically 12-16 ohms).
Step 4: Check for voltage at injector connector with key on; should be battery voltage.
Step 5: Perform a injector balance test or use a noid light to verify injector pulse.
