Cylinder 5 Injection Pulse Offset Not Learned

Check these first

• The cylinder 5 injector offset learning not running
• A cylinder 5 injector out of balance beyond the learn window
• A compression or valve fault on cylinder 5
• A control module that cannot store the cylinder 5 learned value

What to do next

1. Scan all modules and read the cylinder 5 injection pulse offset status
2. Compare the cylinder 5 offset with the other cylinders
3. Run a compression test on cylinder 5
4. Test the cylinder 5 injector balance against the other injectors
5. Replace the cylinder 5 injector if the offset will not learn
6. Clear the code and retest
