Questions

The 1999–2005 engines rely on a 16-tooth tone wheel on the crankshaft and specific sensor configurations (CKP/CMP) that communicate with the earlier powertrain control modules. Your factory 2006 Grand Cherokee requires an engine built for the newer sensor system and 32-tooth tone wheel specs, meaning the electrical signals, reluctor rings, and computer synchronization are completely incompatible out of the box.
