Ever had your 2003 Honda Civic feel a bit… off? Maybe the “Check Engine” light decided to pay you a visit, or your fuel economy isn’t what it used to be. Chances are, a tiny but mighty component – the camshaft position sensor – might be the culprit. This unsung hero plays a crucial role in your engine’s performance, ensuring everything runs smoothly.
Finding the right replacement for your specific vehicle, especially a classic like the 2003 Honda Civic, can be a bit like finding a needle in a haystack with so many options out there. That’s why we’ve put together a comprehensive guide, reviewing 10 popular camshaft position sensors. While we’ve included a variety of options, always double-check the fitment for your exact 2003 Honda Civic model (typically 1.7L engine) before making a purchase. Let’s dive in and get your Civic purring again!
What Does a Camshaft Position Sensor Do?
Think of your camshaft position sensor as the eyes and ears for your car’s engine control unit (ECU). It monitors the precise position and speed of the camshaft, which dictates when the engine’s valves open and close. This vital information helps the ECU know exactly when to fire the spark plugs and inject fuel, ensuring optimal combustion, fuel efficiency, and overall engine performance.
Common Symptoms of a Failing Camshaft Position Sensor:
- Check Engine Light: This is often the first sign, usually accompanied by fault codes like P0340.
- Rough Idling or Stalling: Your engine might struggle to maintain a consistent idle speed.
- Difficulty Starting: The car might crank longer than usual before firing up.
- Reduced Fuel Economy: Incorrect timing can lead to inefficient fuel use.
- Engine Misfires or Hesitation: You might feel a noticeable lag or stutter during acceleration.
Ignoring these symptoms isn’t a good idea, as a faulty sensor can lead to further engine issues down the road. Replacing it can often be a straightforward DIY task for the mechanically inclined!
How to Choose the Right Camshaft Position Sensor

- Vehicle Compatibility: This is paramount! Ensure the part number and listed vehicle fitment match your specific 2003 Honda Civic (L4 1.7L engine).
- OEM Part Number Cross-Reference: Look for sensors that cross-reference with common OEM numbers for your Civic like 37840-RJH-006, 37840-PLC-006, or 907-773.
- Quality and Durability: Look for sensors made with high-quality materials and strict manufacturing standards.

User Impressions: General Feedback
When it comes to camshaft position sensors, users consistently look for a few key things: accuracy, durability, and ease of installation. Many DIYers appreciate sensors that are a direct fit, meaning no modifications are needed and the existing wiring harness plugs right in. Reliability is also a huge factor; nobody wants to replace a sensor only for it to fail again quickly. Customers generally praise sensors that come with a good warranty, as it shows the manufacturer stands behind their product. Ultimately, the goal is to get rid of that dreaded “Check Engine” light and restore the smooth, predictable performance of their Honda Civic.
Frequently Asked Questions (FAQs)
Q1: What are the most common symptoms of a bad camshaft position sensor in a 2003 Honda Civic?
A1: The most common symptoms include the “Check Engine” light illuminating (often with codes like P0340 or P0341), rough idling, engine stalling, difficulty starting, reduced fuel efficiency, and a general loss of engine power or acceleration.
Q2: Is it difficult to replace the camshaft position sensor on a 2003 Honda Civic?
A2: For many 2003 Honda Civic owners, replacing the camshaft position sensor is a relatively straightforward DIY task. It typically involves locating the sensor (often near the cylinder head or timing cover), unplugging its electrical connector, unbolting it, and then installing the new one. Clearing the fault codes afterward is also necessary. Many online tutorials and YouTube videos can guide you through the process.
Q3: Where is the camshaft position sensor located on a 2003 Honda Civic?
A3: On most 2001-2005 Honda Civic 1.7L engines, the camshaft position sensor is located on the passenger side of the engine, usually near the top of the cylinder head or integrated into the valve cover, close to the timing belt cover. It will have an electrical connector plugged into it.
Q4: How much does it cost to replace a camshaft position sensor?
A4: The cost of the sensor itself can range from $20 to $100+ for aftermarket options. If you do it yourself, that’s your only cost. If you take it to a mechanic, labor costs can add another $50-$150, depending on their hourly rate and the shop’s policies.
Q5: Can I drive my 2003 Honda Civic with a bad camshaft position sensor?
A5: While your car might still run, it’s generally not recommended to drive with a faulty camshaft position sensor for an extended period. The engine’s timing will be off, which can lead to poor performance, reduced fuel economy, increased emissions, and potentially cause damage to other engine components over time if the misfires are severe.
Q6: What’s the difference between a camshaft position sensor and a crankshaft position sensor?
A6: Both sensors are crucial for engine timing. The camshaft position sensor monitors the position of the camshaft, which controls valve opening and closing. The crankshaft position sensor monitors the crankshaft’s position, which relates to piston movement. Together, they provide the ECU with the precise information needed for ignition timing and fuel delivery.
Q7: Do I need to clear the “Check Engine” light after replacing the sensor?
A7: Yes, after replacing the faulty camshaft position sensor, you’ll need to clear the stored diagnostic trouble codes (DTCs) from your car’s ECU. This can be done using an OBD-II scanner. Sometimes the light will go off on its own after a few drive cycles, but clearing the codes manually is the quickest way to confirm the fix.
Final Thoughts
A well-functioning camshaft position sensor 2003 Honda Civic owners need is essential for maintaining your car’s reliability and performance. Replacing a faulty one can quickly resolve issues like a persistent “Check Engine” light, rough idling, and poor fuel economy. Remember, always double-check the product’s compatibility with your specific 2003 Honda Civic (especially the 1.7L engine) using the OEM part numbers or vehicle fitment tools provided by the seller.
With the right sensor, you’ll be back to enjoying smooth drives and optimal engine efficiency in no time. Happy wrenching!
