Codes p2097 p2196 p2626 came up for my check engine light. Do I need both up stream and down stream o2 sensors?
P2097 Post Catalyst Fuel Trim System Too Rich
P2196 O2 Sensor Signal Stuck Rich
P2626 O2 Sensor Pumping Current Trim Circuit/Open
yeah, you really have a bad O2 sensor

O2 Sensor in manifold has failed, replace it and have computer reset, hope this helps, let me know
SOURCE: sensor 1 bank has an open circuit
it is the O2 sensor in the manifold that went bad. it is an easy fix but i wouid recommend taking in to somwere other than the dealer to save you money. this is small problem that will only effect your gas milage a little
SOURCE: my check engine light came on it said P2626
This is an O2 sensor failure with the sensor located in the manifold. The associated heater probably failed causing the sensor to fail.
SOURCE: I got 2 codes off the check engine OEM today...
It has two sensors. Bank 1 Sensor 1 is inside the engine bay under the metal heat shield on the front of the engine. Check out NTK sensors online. The one you need will be a 4 wire sensor. The NTK part number is 24588.
SOURCE: i have five codes P2237
P2237 P2196 P2271 P0030 P0171
These are all O2 sensor trouble codes, except P0171 which is a fuel trim code,
You have a bad 02 sensor - up stream - Bank 1 Sensor 1.
Replace it, then road test. The engine computer has a 'default' fuel trim it uses when an O2 sensor fails so it can protect the catalytic converter. If this hasn't been going on too long, good chance simply replacing the O2 sensor will remedy your problem.
