The connector to the crank sensor has melted on the crank sensor. Can the connection be repaired without replacing the complete engine harness?

Hello,

Yes, it can. You should be able to get a replacement Crankshaft Position Sensor [CKP] and a new CKP electrical connector pigtail at your local auto parts store. Disconnect the negative battery terminal to your battery and snip on of the wires going to the CKP electrical connector. Using a good quality butt connector, splice the exact wire on the new CKP electrical connector to the vehicle's wiring harness. Repeat for all the wires then reconnect the negative battery cable to the battery. In the diagrams down below I have included the instructions from the vehicle manufacturer for the removal and installation of your vehicle's CKP. Please go through this guide and get back to us with how everything turns out.

Thanks,
Alex

Hello again,

In the diagrams down below I have included the 2 pages of the Powertrain wiring diagrams that have the Crankshaft Position Sensor[CKP] circuit in it. I have also included the Original Equipment Manufacturer[OEM] part number and labor time for CKP Repair and Replace for your vehicle. As you can see from the wiring diagram the CKP circuit consists of three wires that can be easily cut and a new CKP electrical connector pigtail spliced together with little to no difficulty at all. Please keep us informed as to how everything turns out.

Thanks,
Alex
