Toyota Echo DIY: How to change manual trans fluid Added Mar 4, 09 by tdutzi

How to change O2 sensor in Toyota echo This is my firstattempt at posting a DIY. Hope it is helpful. This DIY will provide step by step instructions to change the Oxygen Sensor located in Bank1 Sensor 2. This oxygen sensor is located behind the catalytic converter. The reason I had to change the oxygen sensor is because my check engine light was triggered. I used an OBDII scanner to scan for error codes. The code I had was PO141 which shows that thesensor is faulty. The shop manual I have for the echo states that the resistance of the Oxygen Sensor should be tested with an Ohmeter to confirm that the sensor is indeed bad. If out of tolerance the sensor can be replaced. I ordered my sensor directly from Toyota. It ran $167 after taxes. Note: There is a number stamped onto the oxygen sensor that you will need when ordering. Below are the stepsI followed to test and remove the oxygen sensor.
