Is Your G20 Running Rough? It Could Be the Intake Air Temp Sensor.
If your 1994-1995 Chevrolet G20 is suddenly getting bad gas mileage, idling poorly, or hesitating when you step on the gas, a bad Engine Intake Manifold Temperature Sensor might be the problem. This small, inexpensive sensor plays a big role in how your engine performs. When it fails, it sends incorrect information to your van's main computer, leading to a variety of noticeable issues.
Check Engine Light is a Key Sign
The most common sign of a failing intake temperature sensor is the check engine light turning on. The computer will store a diagnostic trouble code, most often P0112 (sensor circuit low) or P0113 (sensor circuit high), which can be read with a simple OBD-II scanner.
Choosing the Right Aftermarket Sensor for Your G20
For a straightforward part on a workhorse van like the '94-'95 G20, you don't need to pay high dealership prices for an OEM sensor. Reputable aftermarket brands provide reliable performance at a much lower cost. The key is to choose a brand known for quality electronics.
- Standard Ignition: A well-known and trusted brand in the aftermarket world, often considered a go-to for reliable electronic components like sensors. They offer a good balance of quality and value.
- True Tech: This brand typically offers a more budget-friendly option. While it can be a good choice if cost is the primary concern, it may not have the long-standing reputation of a brand like Standard Ignition.
Before you buy a new sensor, check the electrical connector on the old one. Sometimes, the issue is just a loose connection or corrosion on the pins. Cleaning the connector and ensuring it's plugged in securely can sometimes fix the problem without needing a new part.
