Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.
The code U1262 can be set due to any of the following concerns.
Differential Pressure Feedback EGR (DPFE) Sensor
Fuel Tank Pressure (FTP) Sensor
Powertrain Control Module (PCM)
Powertrain Control Module (PCM) Power Relay
Powertrain Control Module (PCM) Power Relay Circuit
Vehicle Reference Voltage (VREF) Circuit

When I turn on the key the pcm relay is chattering
Expert:  Ron replied 1 year ago.
In most cases when the relay chatters this means it not receiving a good ground. Start with checking the ground G102 from the PCM relay to where the ground connects. The ground G102 is located on right rear fender apron. See its location in the link below, copy and paste the link to your browser to open it.
The ground is number 42 in the diagram.
