P1605 Toyota - & P071 Toyota simultaneously

Question

Hi,

Am getting both P1605 and P071 on my toyota vitz 1299cc of 2008. This was first intermittent and now it is more or less permanent

Plz advise on course of action

Answer 1

P1605 Engine stall history (rough idle)

P0171 Fuel trim too lean

Lean condition such as low fuel pressure or engine starving for fuel,  There also  vacuum leak that can cause the lean condition, what ever is making the vehicle to run very lean creating the rough idle should be inspected, look for any vacuum hose or leak intake leak

Fuel pressure, or better yet fuel volume, change out the fuel filter and retest the system
