7 Top Camshaft Position Sensors for Your 2007 Hummer H3: Restore Engine Performance!
Is your trusty 2007 Hummer H3 acting a bit sluggish? Maybe that dreaded “Check Engine” light has popped up, or you’re experiencing some rough idling? These could be tell-tale signs of a failing camshaft position sensor. This small but mighty component plays a crucial role in your engine’s performance, helping the Engine Control Unit (ECU) understand your camshaft’s rotation and precisely time fuel injection and ignition. When it goes bad, your H3’s performance can take a serious hit.
Finding the right replacement for your 2007 Hummer H3 camshaft position sensor is key to getting your SUV back to its peak. With so many options out there, it can feel like navigating a desert trail without a map. That’s why we’ve scoured the market to bring you a hand-picked selection of top-notch camshaft position sensors known for their reliability, fit, and performance. Let’s dive in and find the perfect fix for your Hummer!
Why a Healthy Camshaft Position Sensor Matters
Your camshaft position sensor (CPS) works in tandem with the crankshaft position sensor to send vital information to your Hummer’s ECU. This data tells the computer exactly where the pistons are in their cycle, allowing for optimal fuel delivery and spark timing. Without accurate signals from the CPS, your engine can suffer from a range of issues, including:
- Hard starting or no-start conditions
- Rough idling or stalling
- Reduced fuel economy
- Engine misfires
- Decreased power and acceleration
- The dreaded “Check Engine” light, often accompanied by codes like P0340 (Camshaft Position Sensor Circuit Malfunction).
Replacing a faulty 2007 Hummer H3 camshaft position sensor isn’t just about clearing a dashboard light; it’s about restoring your vehicle’s reliability, efficiency, and overall drivability.

FAQ Section
Q1: What does a camshaft position sensor do in my 2007 Hummer H3?
A1: The camshaft position sensor (CPS) monitors the rotational speed and position of the camshaft. It sends this information to the vehicle’s Engine Control Unit (ECU), which uses it to precisely time the fuel injection and ignition spark, ensuring your engine runs efficiently and smoothly.
Q2: What are the common symptoms of a bad camshaft position sensor?
A2: Common symptoms include the “Check Engine” light illuminating (often with codes like P0340), difficulty starting your Hummer, rough idling, stalling, decreased fuel economy, sudden loss of power during acceleration, or engine misfires.
Q3: Can I drive my 2007 Hummer H3 with a bad camshaft position sensor?
A3: While your Hummer might still run, it’s generally not recommended to drive with a faulty CPS for an extended period. It can lead to severe engine performance issues, potential damage to other engine components due to improper timing, increased emissions, and unreliable starting.
Q4: Is replacing the camshaft position sensor a difficult DIY job for a 2007 Hummer H3?
A4: For many 2007 Hummer H3 models, replacing the camshaft position sensor is considered a relatively straightforward DIY task. The sensor is usually located on the engine block or cylinder head and is held in place by one or two bolts. It’s often a “plug-and-play” replacement, but always refer to your vehicle’s service manual or a reliable repair guide for exact location and procedure.
Q5: How much does a replacement 2007 Hummer H3 camshaft position sensor typically cost?
A5: The cost of the sensor itself can vary, usually ranging from $20 to $100 depending on the brand (OEM vs. aftermarket) and quality. If you have it professionally installed, labor costs would be extra, typically ranging from $50 to $150 or more, depending on shop rates and the sensor’s accessibility.
Q6: What’s the difference between a camshaft position sensor and a crankshaft position sensor?
A6: Both are vital for engine timing. The camshaft position sensor tells the ECU the exact position of the camshaft (which controls valve opening/closing), helping to determine which cylinder is ready for fuel and spark. The crankshaft position sensor monitors the crankshaft’s speed and position (which directly relates to piston position). Together, they provide the complete picture for precise engine control.
Q7: Will replacing the camshaft position sensor clear my “Check Engine” light automatically?
A7: In many cases, after replacing the faulty sensor, the “Check Engine” light may turn off on its own after a few driving cycles. However, it’s best practice to use an OBD-II scanner to clear any stored trouble codes (like P0340) manually after the replacement to ensure the ECU resets and monitors the new sensor correctly.
