Toyota Tacoma Engine Camshaft Position Sensor Guide (2016-2023)
Solving stalling, rough idle, and check engine lights on your 3rd Gen Tacoma.
- The 3.5L V6 engine has four distinct camshaft position sensors; identify the correct one before buying.
- Denso is the OEM supplier; choosing Denso, Delphi, or NGK aftermarket parts is the most reliable option.
- Replacement is simple (one 10mm bolt), making it an easy DIY job for most owners.
- Be aware of TSB T-SB-0073-18, which addresses oil leaks from the sensor's mounting bolt holes on 2016-2018 V6 models.
Is Your Tacoma Stalling or Running Rough?
A failing camshaft position sensor is a common issue that can cause a variety of frustrating engine problems. Because this sensor's data is so important for engine timing, even a small glitch can make your truck hard to drive. Symptoms often appear suddenly and can include difficulty starting the engine, unexpected stalling at idle, rough running, poor acceleration, and a noticeable drop in fuel economy. In nearly all cases, a faulty sensor will trigger the Check Engine Light on your dashboard.
Important: Check for Oil Leaks & Recalls
TSB T-SB-0073-18: Some 2016-2018 V6 Tacomas may develop an oil leak from the camshaft position sensor bolt holes, not the sensor itself. This requires a specific fix outlined by Toyota. Check the area around the sensor for any signs of leaking oil.
Crankshaft vs. Camshaft: A recall was issued for the crankshaft position sensor on some 2016-2017 V6 models (NHTSA 17V356), which could also cause stalling. This is a different part. Verify which sensor is causing your issue before ordering parts.
Choosing the Right Aftermarket Sensor
When replacing a critical engine sensor, quality matters. While many brands are available, they are not all created equal. Using a low-quality sensor can lead to it failing quickly, performing poorly out of the box, or causing new, hard-to-diagnose problems.
Brand Quality Tiers for Toyota Tacoma
- OEM / Top Tier (Recommended): The original sensor in your Tacoma was made by Denso. Buying a Denso-branded sensor from an aftermarket supplier is the safest way to ensure original quality and fit without paying dealership prices. Other top-tier brands with a strong reputation for reliability in Japanese vehicles are Delphi and NGK.
- Reputable Aftermarket: Brands like Beck Arnley and Standard Ignition (SMP) have a long history. Beck Arnley often re-packages OEM parts (like Denso), which can be a great value, but there's a chance you could get a part from a different supplier. These are generally a safe bet but stick to the top tier if possible.
- Economy Brands: Dorman, URO Parts, Holstein, and other lower-priced brands are available. While tempting, it's a gamble for a sensor this important. Forum posts and mechanic experiences often warn that these parts can have a higher failure rate. For the small cost savings, it's usually not worth the risk of having to do the job twice.
Pro Tip: Identify the Correct Sensor Before You Buy
The 3.5L V6 has FOUR sensors, and they are not all the same. You must identify which one is faulty, usually via the specific OBD-II code (e.g., P0348 for Bank 2, Intake). The sensors are located:
- Bank 1 (Passenger Side): One upper (Intake), one lower (Exhaust).
- Bank 2 (Driver's Side): One upper (Intake), one lower (Exhaust).
Pay close attention to the part itself. Three of the four sensors have a straight electrical connector, but the Bank 1 (passenger side) intake sensor has an angled connector. Always match the new part to the old one you are replacing.
Typical Replacement Costs
Replacing a camshaft position sensor is a straightforward job. The labor cost is low, making it a wise investment to use a high-quality part.
| Part/Service | Estimated Cost |
|---|---|
| New OEM (Denso) Sensor | $90 - $175 |
| New Aftermarket Sensor | $25 - $130 |
| Shop Labor | $50 - $100 |
Frequently Asked Questions
How many camshaft sensors does my 2016-2023 Tacoma have?
If you have the 3.5L V6 engine, your truck has four camshaft position sensors. If you have the 2.7L 4-cylinder engine, it has two sensors.
Is Denso the same as the original Toyota part?
Yes. Denso is the Original Equipment Manufacturer (OEM) for Toyota's camshaft position sensors. A sensor in a Denso box is the same quality as one from a Toyota dealership, often at a lower price.
Can I drive my Tacoma with a bad camshaft position sensor?
You can, but it's not recommended. A failing sensor can cause the engine to stall at any time, which is a safety risk. Driving with the issue can also cause poor fuel economy and potentially damage other components like the catalytic converter over time. You should replace it as soon as possible.
What are the common trouble codes for a bad sensor?
The most common code is P0340, which indicates a general fault in the sensor circuit. More specific codes like P0345 (Bank 2) or P0348 (Bank 2, Sensor 'A'/Intake) can help you pinpoint exactly which of the four sensors has failed.
