ML320 P0222 Code Help?
Hello All. I have a 2002 ML320 Designo Ed. with approx. 116,000 easy miles on her. The truck starts and idles fine but has been acting like its in "limp" mode (lags upon accelerating). I replaced the MAF and I am not getting a code for that. I replaced the O2 sensors in the rear and I am not getting a code for that either. I am getting a P0222 code (Throttle/Pedal Position Sensor/Switch "B" Circuit Low). Replaced the TPS and it will work for about 3 months – then the same thing happens. I have replaced the TPS 2x in last 6 months (Hella part from NAPA) and it is doing it again. This (3rd) time, replaced withe OEM part from the dealer and it still acts the same way – Lagging acceleration and throws the P0222 code after I reset it. Any help would be appreciated. Thx, Nutso06
