Restore Peak Performance to Your GM Vehicle
Is your 2007 GMC Yukon, Silverado, or other compatible GM vehicle suffering from frustrating issues like a persistent check engine light, rough idling, stalling, or a no-start condition? These are classic signs of a failing Engine Control Module (ECM). As the brain of your vehicle’s engine, a faulty ECM can disrupt everything from fuel delivery and spark timing to transmission shifting, leading to poor performance and failed emissions tests. This isn’t just an annoyance; it’s a critical component failure that needs a reliable solution.
This replacement 2007 Yukon Engine Control Module, part number 19210738, is the definitive fix. We take the guesswork and high dealership costs out of the equation. Before we ship it, we program the module with the latest official GM software updates, specifically matched to your vehicle’s VIN. This ensures seamless integration and optimal function right out of the box, restoring the power, efficiency, and reliability you depend on.
Case Study: A Tricky Diagnosis
I remember a 2007 Tahoe that came into my shop with an intermittent stalling problem that had stumped two other mechanics. It would run fine for days, then suddenly die at a stoplight. There were no consistent trouble codes, just a ghost in the machine. After checking all the usual suspects—fuel pump, crank sensor, wiring—I focused on the ECM. On these specific GM trucks, the ECM is located under the battery tray, an area prone to moisture and corrosion from battery leaks. Sure enough, a close inspection revealed faint corrosion on the ECM case. We installed a new, properly programmed module, and the problem vanished for good. It’s a reminder that sometimes the most complex electronic issues have a straightforward, physical root cause.
Is Your Vehicle Showing These ECM Failure Signs?
A failing ECM can manifest in numerous ways. If you’re experiencing any of the following, this module is likely the solution you need. Look out for Diagnostic Trouble Codes (DTCs) such as P0601, P0602, P0606, or U0100.
- ✔ Check Engine Light is on or flashes intermittently
- ✔ Engine stalls, stumbles, or misfires
- ✔ Noticeable loss of engine power and acceleration
- ✔ Reduced fuel economy
- ✔ Transmission shifting issues or harsh shifts
- ✔ Vehicle will not start, even with a good battery and starter
- ✔ Communication errors with diagnostic scan tools
A Straightforward Guide to Installation
Replacing the ECM on most compatible trucks and SUVs is a job a confident DIYer can handle in under an hour. This pre-programmed module saves you a trip to the dealer. Always consult a service manual for your specific vehicle, but here is a general guide for a 2007 Yukon/Tahoe/Sierra:
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the ECM: On most trucks and SUVs listed, the ECM is found on the driver’s side, in front of the wheel well, mounted to a bracket beneath the battery tray. You will need to remove the battery to access it.
- Disconnect Connectors: Carefully release the locking tabs and unplug the wiring harness connectors from the old ECM. Inspect the connectors for any signs of corrosion or damage.
- Remove the Old Module: Unbolt the old ECM from its mounting bracket.
- Install the New Module: Mount your new, pre-programmed ECM onto the bracket and securely plug in the wiring harnesses. Ensure they click into place.
- Reconnect and Relearn: Reinstall the battery and reconnect the negative terminal. You may need to perform a simple security relearn procedure (often called a Passlock or Passkey relearn), which typically involves turning the key to the ‘ON’ position for 10-15 minutes. This allows the new ECM to sync with your vehicle’s anti-theft system.

Frequently Asked Questions
Do I need to do anything after I purchase?
Yes. After your order is complete, you MUST reply to our confirmation email or message us with your vehicle’s 17-digit VIN. We cannot program and ship the module without it.
Is this module truly plug-and-play?
Because it comes programmed to your VIN, it eliminates the need for expensive dealer tools. In most cases, you will only need to perform a simple security relearn procedure, which can be done at home without any special tools. Instructions are readily available online for your specific model.
Will this fix my specific problem?
This module is a direct fix for a faulty ECM. While it resolves the vast majority of issues listed, including P0601 codes, it’s crucial to ensure your vehicle has been properly diagnosed. This part will not fix issues caused by other faulty components like bad sensors or wiring problems.
Where is the ECM located on my 2007 Yukon?
On the 2007 GMC Yukon, Yukon XL, Tahoe, and Suburban, the Engine Control Module is located on the driver’s side of the engine bay, mounted to a bracket directly underneath the battery tray.
What is the difference between an ECM and a PCM?
ECM (Engine Control Module) and PCM (Powertrain Control Module) are often used interchangeably. A PCM controls both the engine and the transmission, while an ECM technically only controls the engine. For most modern GM vehicles like the 2007 Yukon, this module functions as the PCM, managing both systems.
