Honda Ridgeline Crankshaft Position Sensor Guide (2006-2015)
Diagnose and choose the right crankshaft sensor to fix stalling and starting issues on your Ridgeline.
- A failing crankshaft sensor can cause critical issues like stalling and no-starts.
- For Honda sensors, strongly prefer OEM supplier brands like Denso or NGK/NTK to avoid repeat failures.
- Before replacing the sensor, inspect the wiring connector for corrosion, which can cause identical symptoms.
- A 'relearn' procedure with a scan tool may be required after installation for the computer to recognize the new sensor correctly.
Is Your Ridgeline Stalling or Not Starting? It Could Be the Crankshaft Sensor.
A failing crankshaft position sensor is a common reason for a Honda Ridgeline to develop serious running problems. When this sensor starts to go bad, it can leave you stranded. Recognizing the symptoms is the first step to getting your truck running reliably again.
Symptoms of a Failing Crankshaft Position Sensor
- Check Engine Light: This is often the first warning. You will likely see codes such as P0335 (no signal) or P0339 (intermittent signal). 🎬 Watch: How to diagnose these specific trouble codes step-by-step.
- Engine Will Not Start: The engine may crank over but fail to start because the computer doesn't know when to create spark and inject fuel.
- Sudden Stalling: The engine may cut out unexpectedly while driving, which is a serious safety risk.
- Rough Idle and Misfires: Your truck may shake, idle poorly, or feel like it's stumbling as the engine timing becomes erratic.
- Poor Acceleration: A loss of power and sluggish acceleration are common as the computer struggles with incorrect sensor data.
Important: Check for Corrosion First!
Honda has noted in a Technical Service Bulletin (TSB 16-011) for other models with similar engines that corrosion between the engine wire harness and the crankshaft sensor connector can cause the exact same symptoms and trouble codes (P0335/P0339). Before buying a new sensor, unplug the connector and inspect it carefully for any green or white corrosion. Cleaning the connection or replacing a corroded connector pigtail might solve your problem.
Choosing the Right Aftermarket Sensor: Brand Matters
For critical electronic sensors on Honda engines, brand choice is extremely important. Using a low-quality, unproven sensor can lead to the same problems returning quickly, or even create new ones. Based on owner feedback and mechanic recommendations, it is strongly advised to use a sensor from an Original Equipment Manufacturer (OEM) supplier.
Brand Quality Tiers for Honda Ridgeline
Tier 1 (OEM Supplier): These brands make the original part for Honda. They offer the best fit and reliability. For your Ridgeline, this includes Denso and NGK (also sold as NTK). Choosing one of these is the safest bet for a lasting repair.
Tier 2 (Reputable Aftermarket): Brands like Delphi, Standard Motor Products (SMP), and Hitachi have a long history of producing quality electronic components and are a solid second choice if an OEM supplier part is not available.
Tier 3 (Economy): Brands like Dorman, Walker, and other store brands are more budget-friendly. While they may offer a lifetime warranty, their performance and longevity can be inconsistent for critical sensors on Honda vehicles. It is generally recommended to avoid this tier for this specific part to prevent repeat failures.
Pro Tip: What is a "Relearn" Procedure?
After replacing the crankshaft sensor, your Ridgeline's computer may need to perform a "CKP Pattern Learn" procedure. This calibrates the new sensor to the engine. While some vehicles do this automatically, others may require a mechanic with a compatible scan tool to initiate the procedure. Failure to do this can sometimes result in a persistent check engine light.

The cost can vary depending on the brand you choose and whether you do the job yourself or hire a professional. The sensor itself is located behind the timing belt covers, making labor a significant part of the cost.
| Part or Service | Estimated Cost |
|---|---|
| New OEM Sensor | $163 - $304 |
| New Aftermarket Sensor | $40 - $474 |
| Shop Labor | $139 - $204 |
| Total Professional Replacement | $303 - $508 |
Frequently Asked Questions (FAQ)
Where is the crankshaft position sensor located on a 2006-2015 Honda Ridgeline?
The sensor is located on the front of the engine, down low near the crankshaft pulley. To access it, you typically need to remove the splash shield and the lower timing belt cover.
🎬 Watch this walkthrough for diagnosing a Ridgeline that won't start.Can I drive my Ridgeline with a bad crankshaft sensor?
It is not recommended. The most dangerous symptom is sudden engine stalling, which can happen at any speed and lead to a loss of power steering and brakes. If your truck is showing signs of a bad sensor, it's best to get it repaired as soon as possible.
Is it better to buy an OEM or aftermarket sensor?
For this specific part on a Honda, it is highly recommended to buy a sensor from an OEM supplier like Denso or NGK/NTK. These sensors are engineered to the exact specifications required by your Ridgeline's computer, minimizing the risk of future problems.
Is there a recall for the crankshaft on the Honda Ridgeline?
Yes, but it's for the crankshaft itself, not the sensor. NHTSA recall 23V-751 affects some 2017 and 2019 Ridgeline models for an improperly manufactured crankshaft that can cause the engine to seize or fail. While this recall does not apply to the 2006-2015 generation, it's important not to confuse a sensor failure with this more severe mechanical issue.
