2009 Toyota 4Runner Problems

Car Won't Start Due to Worn/Corroded Solenoid Contacts in Starter

If the car will not start, the most likely problem is worn or corroded solenoid contacts in the starter. Usually, these parts can be replaced without purchasing a new starter.

Check Engine Light Due to Failed Charcoal Canister

The evaporative emission (EVAP) system may illuminate the vehicle's Check Engine Light due to intermittent failure of the charcoal canister purge control solenoid valve or canister failure. Upon failure of the charcoal canister, debris may circulate around the EVAP system causing other emission control problems.

The noise is from the secondary air pump, which sends hot air to the catalytic converter when the engine is cold. This allows the catalytic converter to clean exhaust better, and lower emissions while the engine is warming up.

Pump failure may result in:

Fixing the issue involves removal of the intake manifold, and replacement of the secondary air pump.
