The 2001 Toyota Tacoma uses two oxygen sensors located in the Motor lorry's exhaust tube. One sensor is located forward of the catalytic converted, and the other is located aft of the converter.
Instructions
Existing vehicles are equipped with O2 sensors in the exhaust action. The sensors detect the immensity of O2 in the exhaust gases, and correspondence the info to the vehicle's electronic state module. The ECM uses the dirt to adjust the fuel/air combination for maximum performance.
1. Open the vehicle and let it gallop for encompassing 10 minutes. This causes the exhaust cylinder to heat up and expand. Without doing this, the O2 sensors might be further tight to remove.
2. Up thrust the vehicle using a jack, and agency the Motor lorry with four jack stands. You can skip this method, on the other hand the daily grind Testament be extended hard owing to you Testament own less amplitude to manoeuvre underneath the Motor lorry.
3. Locate the forward oxygen sensor by following the exhaust pipe from the catalytic converter, approximately 6 inches, toward the front of the vehicle. The sensor is inserted into the pipe on the top side.
4. Follow the electrical wire from the sensor, approximately 8 inches to the electrical connector, and disconnect the wire.
5. Remove the two nuts from the bolts that attach the sensor to the tail pipe, and pull the sensor out of the pipe. Insert the new sensor and replace the nuts. Connect the lead wire from the sensor to the electrical connection from which you unplugged the old sensor.
6. Follow the tail pipe from the catalytic converter, about 8 inches toward the rear of the truck, to locate the aft oxygen sensor. Repeat steps 4 and 5 to replace this sensor.
7. Lower the vehicle from the jack and take it for a test drive. Ensure that the check engine light does not come on, which might indicate that you installed the oxygen sensors incorrectly.
