Question

2000 Ford Explorer 5.0.
PO 340.
Camshaft Position A Bank 1.
Circuit malfunction
System too Lean Bank 1.

Answer 1

Hi there,

This could indicate a timing issue with bank 1. The cam sensor code will appear if the timing is off, this can also cause a lean fuel mixture on that bank. The other possible issue could be the cam sensor is no good and you need to check for intake manifold leaks on bank 1.
