Brake booster,VSC CEL and traction

Asked by Apr 23, 2016 at 07:52 PM about the 2006 Toyota RAV4 Base

Question type: Maintenance & Repair

Trying to figure this one out. I can hear the vaccum
leak, but I'm curious if the brake booster failing
would cause these light to come on in my Toyota
RAV4? PO171 was the code when I checked.

No not the brake booster. P0171 TOYOTA - Air/Fuel Mixture System Lean Bank 1.... Possible causes - Intake air leaks - Faulty front heated oxygen sensor - Ignition misfiring - Faulty fuel injectors - Exhaust gas leaks - Incorrect fuel pressure - Lack of fuel - Faulty Mass Air Flow (MAF) sensor - Incorrect Positive Crankcase Ventilation (PCV) hose connection.... If the P0171 is combined with the P0174 code, it's very likely that the problem is caused by an intake leak. If there are no intake leaks, the next step is to replaced the air filter and clean the air flow meter. If the problem persist the front oxygen (O2) sensor may need to be replaced.
