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.

2001 Toyota 4Runner Problems
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.
The heater circuit for the oxygen sensor tends to have a higher than normal failure rate. Failure of the oxygen sensor heater circuit will illuminate the Check Engine Light. The internal oxygen sensor heater cannot be repaired, the failed sensor should be replaced to correct this concern.
When a mass air flow sensor problem occurs, resulting in a loss of power or hesitation on acceleration, the Check Engine Light will illuminate, perhaps indicating random cylinder misfire. The mass air flow sensor may respond to cleaning, but replacement of the sensor is best.
On higher mileage vehicles, an engine misfire may develop and/or the Check Engine Light may illuminate due to a failed ignition coil. It is not uncommon to replace all the coils when the first one fails in order to prevent return trips to the repair shop.

2001 Toyota 4Runner Reviews
I have a 2001 Toyota 4-runner two wheel drive v6? I have aprox 250,000 miles and have had to do NOTHING but change the oil and brakes. What a GREAT vehicle. I have always driven Jeep or Lexus. I know they are related but I hope to never own another Lexus. This car if very plain and a little small ..no creature comforts but is hands down the best vehicle I have ever owned. I am the second owner and I bought it in aprox 2005.
I am another victim of poor 3.4 engine design. SLUDGE. Only 1220,000 miles. I have all reciepts from my oil changes and regular service from the Toytoa Dealership.
My very last Toyota.
