My apologies if this was already posted by me. Before I signed up, I asked this question, but my question window disappeared so not sure if it went anywhere.

My vehicle (listed above) failed emissions and the resulting message was the "P018C CHRYSLER - Fuel Pressure Sensor 'B' Circuit Low".

I should be able to replace this part myself, unless the mechanics here feel otherwise. I already have the part, but am having trouble locating the existing one.

Can someone either point me to a diagram or image showing this part in the engine bay or explain it to me? Thanks in advance.

Good afternoon,

I attached the procedure for you for the replacement.

Also, this code could be a low voltage code to the sensor. Verify 5 volts to the sensor connector and the return to the PCM. If they are good, then the sensor is bad.
