Nissan Frontier Engine Camshaft Position Sensor Guide (2005-2024)
Solve stalling, hard starting, and poor engine performance by understanding and choosing the right camshaft sensor for your Frontier.
- For reliable repairs, only use the OEM brand, Hitachi, or a genuine Nissan part.
- The V6 engine has two different camshaft sensors (Bank 1 and Bank 2) that are not interchangeable.
- It is strongly recommended to replace both camshaft sensors and the crankshaft position sensor at the same time.
- Common symptoms include stalling, hard starting, and a Check Engine Light with codes P0340 or P0345.
Symptoms of a Failing Camshaft Position Sensor
When a camshaft position sensor starts to fail on your Nissan Frontier, the signs can range from annoying to leaving you stranded. The most common indicator is the Check Engine Light illuminating on your dashboard. You may also experience sudden engine stalling, especially at low speeds or when coming to a stop. Other symptoms include difficulty starting the engine, rough idling, a noticeable loss of power, and harsh or jerky automatic transmission shifting. These issues occur because the engine's computer is receiving bad data and can't properly time the spark and fuel delivery.
Common Trouble Codes
A code scanner will often show diagnostic trouble codes (DTCs) P0340 (Camshaft Position Sensor Circuit Malfunction Bank 1) or P0345 (Camshaft Position Sensor Circuit Malfunction Bank 2). Bank 1 refers to the passenger side of the engine, while Bank 2 is the driver's side.
Choosing the Right Aftermarket Sensor: A Quality Warning
When it comes to electronic sensors for Nissan vehicles, quality is extremely important. While many budget-friendly aftermarket options are available, Frontier owners and mechanics overwhelmingly report problems with them. Using a cheap, non-OEM quality sensor often leads to the same problems returning in a short time, meaning you'll do the job twice.
Brand Quality Tiers for Your Frontier
- Tier 1 (OEM/OEM-Equivalent): Hitachi. Hitachi is the original equipment manufacturer (OEM) for Nissan's camshaft sensors. Choosing a Hitachi sensor is the safest bet for reliability and compatibility. It is the same part you would get from a Nissan dealership, but often at a lower price. Many owners report that only Hitachi or genuine Nissan parts will permanently fix the issue.
- Tier 2 (Reputable Aftermarket): Brands like Delphi, NGK (NTK), and Standard Ignition (SMP) generally have a better reputation than store-brand parts. However, for this specific sensor on the Frontier, the community consensus strongly favors sticking with the OEM manufacturer, Hitachi.
- Tier 3 (Budget/Store Brands): Brands like Dorman, Duralast, and other low-cost online options are widely discouraged for this repair. Owners frequently report that these sensors fail quickly or don't work correctly out of the box, causing continued frustration and wasted money.
Replace in Sets
Your V6 Frontier has two camshaft position sensors and one crankshaft position sensor. These three sensors work together. It is highly recommended to replace all three at the same time using the same high-quality brand (Hitachi). The sensors tend to have a similar lifespan, and replacing only one can sometimes cause communication issues with the older sensors.
How Much Does a Camshaft Position Sensor Replacement Cost?
The cost can vary depending on the brand you choose and whether you do the work yourself. The replacement is a feasible DIY job for those with basic tools and patience, as the sensors are in a tight spot at the back of the engine.

Frequently Asked Questions
How many camshaft sensors does my Frontier have?
If you have the V6 engine (4.0L or 3.8L), your truck has two camshaft position sensors, one for each cylinder head (Bank 1 and Bank 2). The 4-cylinder engine (QR25DE) has one camshaft position sensor.
Where are the sensors located?
On the V6 engine, the sensors are located at the very back of the engine near the firewall, on the top of each cylinder head. They can be difficult to reach, especially the passenger side sensor. Each is held in by a single 10mm bolt.
🎬 Watch a quick demonstration of a Bank 2 sensor replacement.Are the Bank 1 and Bank 2 sensors the same part?
No. For the 4.0L V6 (VQ40DE), the two sensors are different. One has a straight electrical connector, and the other has an angled connector. It is critical to order the correct sensor for the specific bank you are replacing.
Was there a recall for the camshaft position sensor?
There was a recall (NHTSA ID: 07V527000) for some older Nissan models for a crankshaft position sensor issue that could cause stalling, but it did not specifically cover the 2005+ Frontier camshaft sensors. No specific recalls or Technical Service Bulletins (TSBs) for the 2005-2024 Frontier camshaft position sensor were found during the search.
Do I need to do anything after replacing the sensor?
After installing the new sensor, you should clear the check engine codes with a scan tool. It's also a good practice to disconnect the battery's negative terminal before starting the repair. Always lubricate the new sensor's O-ring with fresh engine oil before installation to ensure a proper seal.
