04 sable trouble code p2197


P2197 is model specific and I don't have the info for your model.
For some Ford products it is for a lean O2 sensor.
If that injector is dead it could cause the code.
A lean O2 code does not always mean the sensor is bad, but that the reading the computer is getting is out of normal range.

I have a 2003 3.0 engine Honda Accord that is giving me trouble codes P2197 P0154 P2254, what do these mean? Thank you.


Here it goes.
P2197 - Front Air Fuel Sensor (O2 sensor) Bank 2 - Sensor 1 Signal stuck lean.

P0154 - Front Air Fuel Sensor (O2 Sensor) Bank 2 - Sensor 1 Heater System Malfunction.

P2254 - Front AIr Fuel Sensor (O2 Sensor) VS Line high voltage.

IF Trouble codes P0134 or P0154 are present diagnose them before code P2254.

The first thing I would do would be check the heater circuit. You will have ground, and 12V+ to the 02 sensor heater line on a cold start. This heats up the oxygen quicker and allows it to operate in the correct amount of time. 9/10 times if there is a heater circuit code it is the oxygen sensor. But 1/10 times it is a blown fuse. So checking the voltage at the sensor is a quick test for P0154.

I would backprobe the signal line when the vehicle is at a full operating temp with a graphing meter (if avail) or use a DVOM. You should see it switch between .1 volts to 1V. It should not continuously move up and down. This indicates the computer is in good fuel control.

Diaginosis the heater circuit first is best because code P2197 can be set from anything that can cause that motor to run lean. (Plugged fuel filter, low fuel pressure/volume, vacume leak).

Hope this gives you a solid path to go on & good luck.

05 tundra, battery went dead with doors locked


The key won't turn in the door lock? Spray some graphite or lubricant into the lock cylinder and work it some. If you have been using the remote all these year and never the key its probably a little rusty.
