1996–2000 Isuzu Hombre PCM 16228016 Programmed to Your VIN

Is Your Truck Running Rough? It’s Time to Check the Brain.

If you’re dealing with a frustrating no-start condition, a check engine light that won’t go away, or an engine that just doesn’t feel right in your 1996-2000 Isuzu Hombre or compatible GM vehicle, the problem often points directly to a failing Powertrain Control Module (PCM). As the central computer, when the PCM starts to fail, it can create a cascade of confusing and costly issues. I’ve seen it hundreds of times in my 20+ years in the shop: customers arrive after replacing perfectly good sensors and parts, only to find the root cause was the PCM all along.

Symptoms of a Failing PCM (Part 16228016)

Your vehicle’s computer is the source of many hard-to-diagnose problems. If you’re experiencing any of the following, a faulty PCM is the likely culprit:

• ✔ Persistent Check Engine Light (CEL) with various codes.
• ✔ Engine cranks but refuses to start.
• ✔ Rough or erratic idling and stalling.
• ✔ Noticeable decrease in fuel economy.
• ✔ Failure to pass an emissions test.
• ✔ Harsh or incorrect automatic transmission shifting.
• ✔ Communication errors with diagnostic scan tools.

Plug-and-Play Installation: Get Back on the Road in Minutes

Installing your new PCM is a straightforward job you can do in your own driveway. Follow these simple steps:

1. Safety First: Disconnect the negative terminal from your vehicle’s battery and wait 10 minutes for the system to discharge.
2. Locate the PCM: On most S10/Sonoma/Hombre models, the PCM is located in the engine bay, on the passenger side near the firewall or fender. On cars like the Cavalier or Grand Am, it may be under the dash.
3. Disconnect the Connectors: Carefully unclip the wiring harness connectors from the old module. Inspect the pins for any corrosion or damage.
4. Remove the Old Module: Unbolt the old PCM from its mounting bracket.
5. Install the New Module: Bolt your new, programmed PCM into place and securely reconnect the wiring harnesses. Ensure they click into place.
6. Reconnect the Battery: Reattach the negative battery terminal. The vehicle is now ready to start.

Expert Pro Tip: Before you condemn your old PCM, perform a ‘wiggle test.’ With the engine running (if possible), gently wiggle the wiring harness connectors at the PCM. If the engine stumbles, stalls, or the check engine light flickers, the problem may be a poor connection or a broken wire at the terminal, not the module itself. Cleaning the connector pins with a dedicated electronic cleaner can sometimes save you the cost of a replacement part.
