An Expert’s Diagnostic Tip
As a technician, I’ve seen countless hours and dollars wasted chasing what seemed to be sensor or wiring issues. A failing PCM can send false signals, making you think you have a bad throttle body or a faulty sensor. One of the classic signs is a cluster of seemingly unrelated error codes. Before you start replacing sensors, check for PCM communication with a quality scan tool. If the module is dropping communication intermittently or has internal fault codes (like P0601), replacing it with a quality, pre-programmed unit like this Programmed 89017734 PCM is the most direct and effective path to a lasting repair.
Frequently Asked Questions
How do I provide my VIN?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We must have your VIN to program the module before we can ship it.
Is this part difficult to install?
The physical installation is typically straightforward, involving disconnecting the battery and swapping the module. However, after installation, you will need to perform a security relearn procedure, which can be done without special tools. A crankshaft variation (CASE) relearn is also recommended and requires a compatible bi-directional scan tool.
