Hello, welcome and thanks for asking your question. My name is*****'m a Certified Auto Technician with 29+ years experience. I will do my best to assist you. please keep in mind that I may need to ask questions of you before I can answer. When you reply please feel free to add as much detailed information as possible pertaining to your concern.

No there is no recalibration of the TPS necessary. IF there is an active code stored in the ECM you will need to diagnose the system to find the cause. Are you going to diagnose yourself? If so, I can post the diagnostic procedure for you..

Keep me posted...

Thank you,

i am going to diagnose it myself. i am trying to find out why it would be throwing this code now when it did not before the motor blew.

Before going any further, check the large connector that is mounted to the firewall just above the fuel filter assembly. Disconnect and reconnect this connector(s) (there may be two) and clear codes to see if the code comes back, in the mean time, I'll get the diagnostic procedure for you....

Thank you,
