Hey so my car is currently acting up, it started off with just the abs, power steering, and vsc lights on then I got to the gym and did a 5 minute drive and the check engine and brake light came on as well. I decided to scan it then my cars rpms went up to 1.5k and stayed there. I proceeded to try and drive home but car went in limp mode, so I turned it off and back on and drove home but it ended up going into limp mode again. The codes I got after scanning it the latest time is
p2127
p2138
p0651
p2422
p1454
battery was at 78% after I did that 5 minute drive as well but I went to auto zone and they said it was good, I took it to advanced and they said it needed to be replaced so I used my own and the voltage was normal? But cca were at 580 instead of 500.

So these are two separate problems. We will address the Throttle/Pedal Position Sensor on this thread please start a new question for the EVAP issues. You need to replace the accelerator pedal position sensor and then clear the odes to get he car out of limp mode, this guide can help explain as well.

P2127: Throttle/Pedal Position Sensor/Switch E Circuit Low
P2138: Throttle/Pedal Position Sensor/Switch D/E Voltage Correlation
P0651: Sensor Reference Voltage B Circuit Open

P2422: EVAP Vent Valve Stuck Closed
P1454: EVAP System Leak Detection Pump System

Here is the location of the sensor an how to change it out. Check out the images (below). Please let us know what happens.
