2000 Toyota 4Runner Problems
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.
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 Oxygen Sensor Heater
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.
Hesitation or Misfire Due to Failed Mass Air Flow Sensor
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.
Misfire and/or Check Engine Light Due to Failed Ignition Coil
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.
Keyless entry stopped working
My keyless entry stopped working. The remotes have fresh batteries and I've already tried the reprogramming list or opening/closing etc. Ideas?
Check Engine Light With Code P0170
Occasionally, the mass air flow sensor can go lean and set a code P0170 for fuel system lean. This in not an oxygen sensor problem. If there are no vacuum leaks, the mass air flow sensor may need to be replaced. Our technicians remind us to use a factory part because the aftermarket rebuilds are very inconsistent.
