Customer Question

I have a 2008 Buick Enclave that currently is throwing a P1516, C0299, and C0242 code. The car in the past has experienced loss of throttle response. I have checked the connections and cleaned the map sensor which returns the throttle response but it happening more frequently.

I am sorry your having this problem

those C codes are more than likely set due to the P1516 code set which is a throttle body code set

most of these throttle bodys codes set are do to bad connections at the throttle body

the best action to take is to unplug the throttle body connector and pack the connector full of dielectric grease picked up at most local auto parts stores and plug it back in

if by chance it still sets this code and the wiring visually to the throttle body looks good replacing the throttle body will correct that issue
