What does error code P0040 mean on a 2004 Chrysler Sebring touring


O2 sensors connections for the front sensors are swapped, open (cut) or shorted out. The PCM may be bad if the sensors and wiring are ok.
If you recently worked on the sensors check your wiring. If not, You probably have a bad O2 sensor or the wiring is at fault.

1999 Jeep Grand Cherokee Laredo 8Cyl4.7L When when driving over 50 miles per hour will lose all power whats wrong?


When you say it loses power, do you mean electrical power or engine power ?
You would need to look at the fuse boxes for a loss of electrical power, and use a scanner or code reader to check the computer for trouble codes for a loss of engine power.

Hi,

Improve the Fixya.com experience for everyone by voting!

Unfortunately, you did not provide a year and a model and I cannot give you a precise response

Translation:

P0040 Upstream Oxygen Sensors (HO2S) Swapped From Bank To Bank

Your heated oxygen sensor is not properly transmitting data to your PCM (onboard computer), You'll need a code scanner that you can borrow for free from AutoZone.

All the best,

Ben
