Received a code 0122 TPS low volt on a 2002 with 301K miles. Last TPS replaced about 80K and three yrs ago. Put the new TPS in from Tim's and calibrated between >. 666 volts and 3. 8 volts. I can not clear the code 0122 and the engine is running as if i had not replaced the TPS. the truck runs like in the limp mode or less. Any ideas before I have to spend $200 to truck it to the dodge dealer. Thanks... .
