A Guide to the 2004-2012 Chevrolet Colorado Neutral Safety Switch
Understand the symptoms of a failing neutral safety switch and learn how to choose the correct new aftermarket part for your truck.
- A primary symptom is the engine not starting in Park but cranking in Neutral.
- A Check Engine Light with code P0705 is a strong indicator of a failing neutral safety switch.
- For 2011 models, check for an open recall (11181) on the shift cable clip, which causes similar symptoms.
- Replacement is a feasible DIY task, but careful alignment of the new switch in the Neutral position is essential for it to work correctly.
Is Your Colorado Having Trouble Starting? It Could Be the Neutral Safety Switch
If your Chevrolet Colorado won't start, starts only in Neutral but not Park, or has non-working reverse lights, a faulty neutral safety switch is a likely culprit. This component, also called a transmission range sensor, is a common point of failure as a vehicle ages. It sends critical information to your truck's computer, including what gear you've selected. When it fails, it can cause a range of frustrating electrical issues, most notably preventing the starter from getting power.
Don't Mistake It for Other Issues
The symptoms of a bad neutral safety switch can sometimes be confused with a dead battery, a bad starter, or an ignition switch problem. Owners of first-generation Colorados also report issues with the PassLock anti-theft system, which can cause similar no-start problems. 🎬 Learn how to fix Colorado Passlock security no-start issues. A common sign pointing specifically to the neutral safety switch is the ability to start the engine in Neutral by wiggling the shifter, but not in Park.
Choosing the Right Aftermarket Neutral Safety Switch
When replacing the neutral safety switch on your 2004-2012 Colorado, you have options outside of the original equipment manufacturer (OEM) part. Aftermarket brands like Rostra Powertrain and Standard Ignition (Standard Motor Products) offer direct-fit replacements.
- Standard Ignition (SMP): Often considered a premium aftermarket brand, Standard parts are known for their quality and are a common choice for professional repair shops. They focus on meeting or exceeding OEM specifications.
- Rostra Powertrain: Rostra is another established brand in the transmission parts industry, providing a cost-effective alternative to OEM and other premium aftermarket parts.
For a component like a neutral safety switch, which can leave you stranded if it fails, investing in a quality aftermarket part from a reputable brand is recommended. While OEM is always an option, a top-tier aftermarket switch from a brand like Standard Ignition often provides comparable quality and reliability for less money. Some forum users have reported fitment issues with lower-cost, unbranded aftermarket connectors, reinforcing the benefit of choosing a well-known brand.

Known Issues and Recalls
While there are no specific recalls for the neutral safety switch itself on the 2004-2012 Colorado, there was a recall for certain 2011 models. Recall 11181 addressed a faulty automatic transmission adjustment clip that could cause the gear shifter's indicated position (PRNDL) to not match the actual gear the transmission was in. This could lead to a no-start condition or a rollaway risk, symptoms that are very similar to a failed neutral safety switch. Before replacing the switch on a 2011 model, it's wise to check with a GM dealer to ensure this recall has been performed.
Installation Pro-Tip
The neutral safety switch is located on the driver's side of the transmission. Replacement requires raising the vehicle safely. A key step is proper alignment of the new switch. The switch must be installed while the transmission is in Neutral to ensure it sends the correct signals. The electrical connectors can be difficult to remove due to a factory-applied glue; gently heating the plug with a heat gun can help soften the glue and prevent breaking the connector.

It is not recommended. The truck may fail to start, leaving you stranded. In rare cases, it could allow the engine to start in gear, creating a serious safety hazard.
Is replacing the neutral safety switch a DIY job?
Yes, for those with mechanical experience. It involves safely lifting the vehicle, removing the shift cable and electrical connectors, and unbolting the switch from the transmission. Proper alignment of the new switch is critical.
What is a P0705 code?
P0705 is a diagnostic trouble code that means "Transmission Range Sensor Circuit Malfunction." This code is a strong indicator that the neutral safety switch has failed or there is a problem in its wiring.
Will a bad neutral safety switch cause transmission shifting problems?
Yes. Since the switch tells the computer what gear is selected, a bad signal can lead to harsh shifting, delayed shifting, or the transmission going into "limp mode," where it gets stuck in one gear.
