A DTC Code P1518 appeared on my '01 Chevy Suburban 2500 2WD 6.0L and at the same time a message saying "Reduced Engine Power". I had a machanic check the wiring and ground connections. The error returned after driving just 35 miles again. My TAC module has a part no. "BD 25173339 C" that I am trying to find used. Online suggests that a number of other vehicle models use the same module, how can I know if I have the correct module? Also I don't know the difference between refrences to TAC, ECM, or PCM modules. Can you help me please?
