Check engine light came on and code P2121 came up.I can't find it in my book anybody know what it means??

 

P2121 is the APPS or whatever that little doohicky that controls how much fuel the engine gets when you push the slender pedal.

"Linkage/throttle positions sensor assembly, accelerator control replaced part # 53031575AH" was what my work order said.

"0.3 hr, time for diag c/s intermit gas pedal did not respond, drb check, fault code P2121, erase code and road test, check apps sensor voltage sweep with drb, replace accel pedal position sensor diesel eng, roat test after repair"

It happened twice on me, and twice on my wife until I took it in. Take it in and it should take about 2 hours to do it. Unless they have to have the part shipped in from somewhere!

Been there, done that.

 

That's my same reply as on TDR. I'm a man of little words.

 

Thanks Again!!
