Injector Circuit Malfunction - Cylinder 8
The P0208 code indicates a malfunction in the electrical circuit of the fuel injector for cylinder 8. This means the powertrain control module (PCM) has detected an abnormal voltage or resistance in the injector circuit, which can prevent the injector from opening properly. Common causes include a faulty injector, wiring issues, or a damaged PCM.
01. Most Common Causes
- Faulty fuel injector on cylinder 8
- Open or shorted wiring in the injector circuit
- Corroded or loose connector at the injector
- Failed PCM (rare)
02. Symptoms You Will Notice
- Engine misfire on cylinder 8
- Rough idle or hesitation
- Check Engine Light illuminated
- Poor fuel economy
03. Step-by-Step Diagnosis
Step 1: Scan for codes and record freeze frame data.
Step 2: Visually inspect the injector connector and wiring for damage or corrosion.
Step 3: Use a multimeter to test injector resistance (should be 11-18 ohms).
Step 4: Check for power and ground at the injector connector with a test light or multimeter.
Step 5: Swap injector with another cylinder to see if the code moves.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended as it can cause misfires, reduced power, and potential damage to the catalytic converter.
How much does it cost to fix?▼
Typically $50-$150 for diagnosis and repair, but can be higher if the injector or PCM needs replacement.
