How to replace o2 pre converter gmc 1500
i dont no
Yes, replace the sensor and have the dash light reset.
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.)
remove and replace.
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
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
The sensor will cost around $75. It will cost another $75 to have it installed and the ECU reset.
