Alternative Fuel Vaporizer C Performance

Check these first

• A vaporizer C that cannot reach its commanded output
• Low alternative fuel pressure at vaporizer C
• A restricted vaporizer C coolant or fuel passage
• A worn vaporizer C internal component
• A control module that cannot drive vaporizer C

What to do next

1. Read vaporizer C performance data on a scan tool
2. Command vaporizer C and compare output to commanded
3. Check alternative fuel pressure at vaporizer C
4. Inspect vaporizer C for restriction or wear
5. Replace vaporizer C if output stays low
6. Clear the code and retest
