Yes, replace the sensor and have the dash light reset.
remove and replace.
Bank 1 (one) is the side in front of car (Bank 2 is rear, firewall side) 02 sensor 1 is upstream, on exhaust manifold (02 sensor 2 is downstream, by cat. conv.)
what do i have to do to replace the front drive axles on a 2004 ford ecscap???
Replace the upstream O2 sensor which is on the exhaust manifold
A Bosch O2 sensor, from NAPA, is $91 here in southwest Washington.
LOCATE THE SENSOR IN QUESTION THEN WARM THE ENGINE SLIGHTLY TO MAKE REMOVAL OF THE 92 SENSOR EASIER THEN USING A 02 SOCKET OR 7/8 WRENCH LOOSEN THE 02 SENSOR AND REMOVE IT ALSO DISCONNECT THE WIRING CONNECTOR.
Replace the downstream O2 sensor
The sensor will cost around $75. It will cost another $75 to have it installed and the ECU reset.
Replace fuel filter and check the 02 sensor if the check engine light is on it's probably the 02 sensor run a diagnostic test to be sure
