E13-Oxygen sensor voltage stays between 0.307 and 0.609 volts for 64 seconds. Engine was at normal operating temperature at a speed over 800 RPM.
E44-Right oxygen sensor was lean for more than 50 seconds when engine was warm and at 800 RPM or greater.
E52-PCM has lost primary battery power.
E58-Pass Key fuel enable was not correct.
F47-PCM has received bad data from IPC for 3 seconds while engine speed was 500 RPM or more for 3 seconds.
F48-EGR open command was given during off idle operation. EGR opening should cause the mixture to be slightly richer because of the low oxygen content of exhaust gas. Vehicle speed was over 35 MPH and engine was warm.
Good luck and hope this helps, keep me posted be glad to answer any questions you may have.

First do you have a sterring wheel puller. Can't remove the steering wheel without one. Quite an involved job including snaking the electrical connector end through the steering column. I wouldn't recommend it to the novice

E26 - Shorted Throttle Switch Circuit
E27 - Open circuit in throttle switch
On these 2 codes replace the TPS and clear codes (throttle position sensor).
E52 PCM/ECM Memory Reset
Have u cleared the memory? don't worry about this code.
