P0174 02 Toyota Sienna What does this code mean?

Question

On dashboard my Brake light, ABS light and engine light are all on. The OBDII codes are:
P0174
P0420
P1130
What does this mean?

Answer 1

P0174 Fuel trim lean Bank 2

P0420 Catalytic below threshold Bank 1

P1130 A/F (airflow) sensor circuit range / perfromance malfucntion

Whenever the CK ENG LT comes on the ABS and Trac are disabled, the reason is for safety the vehicle is not at manufactuer operating specification.A P0174 for a lean code condition will set a P0420 and a P1130, the first inspection to look for are vacuum leak that gets past the MAF , rupture vacuum hoses disconnected vacuum hose, are the first to be inspected for,
