1. Common problems that may cause lean codes:
* Low fuel pressure
* Partially blocked fuel injectors (Refer to Fuel System Pressure Test (Gasoline Engines Only) or
Fuel System Pressure Test (LPG ENGINES ONLY), depending on lift truck fuel system configuration)
* Manifold vacuum leaks
* Defective oxygen (O2) sensor (see DTC 522735-X,
Electrical System, General Maintenance and Diagnostic Data, Diagnostic Trouble Codes, Page

* A misfire on one or more cylinders
* Exhaust leak ahead of the oxygen (O2) sensor
* Faulty MAP sensor (see DTC 106-X,
Electrical System, General Maintenance and Diagnostic Data, Diagnostic Trouble Codes, Page

2. If DTC continues to be displayed after examining the above, go to CAUSE C.
