Fuel Tank Pressure Sensor Buying Guide — Cheap OEM Replacement Parts for Sale | REVXSC
Looking for cheap fuel tank pressure sensors that won't fail in 6 months? Whether you're chasing P0452 fuel tank pressure sensor low input, fuel tank pressure sensor location ford explorer, EVAP system pressure sensor replacement cost, how to test fuel tank pressure sensor, FTP sensor vs fuel pressure sensor difference, this guide covers what to buy, what to skip, and how to make sure the part you order actually fits your truck or car. Every fuel tank pressure sensor sold at REVXSC ships with a verified year/make/model/engine fitment table — no guessing.
What fuel tank pressure sensors actually do
In one sentence: the EVAP system sensor that monitors fuel tank pressure to detect vapor leaks and verify EVAP test results. When they wear out, you'll typically feel it before you see it — your car starts telling you something is wrong, and ignoring it gets expensive.
Signs you need new fuel tank pressure sensors
- check engine light with codes P0450, P0451, P0452, P0453
- EVAP system monitor failing readiness for emissions test
- fuel smell or vapor odor with no visible leak
- long crank times after refueling
- incorrect fuel pressure data on a scan tool
If you tick more than one box, replace before it leaves you on the side of the road. The repair gets a lot cheaper when you catch it early.
Also known as
Depending on the shop manual, region, or supplier you're reading, fuel tank pressure sensors are also called: FTP sensor, EVAP pressure sensor, tank pressure sensor, fuel vapor pressure sensor, EVAP system sensor. They all refer to the same component — when you're cross-referencing OEM and aftermarket part numbers, watch for these naming variations so you don't double-order the same item.

OEM vs aftermarket: which to choose
For fuel tank pressure sensors, the brand actually matters. Standard Motor Products and NTK supply major automakers as OEM suppliers — when you buy their boxed retail product, you're getting the same engineering and tolerances. OE-spec sensors match exact pressure range and connector style, while aftermarket equivalents from NTK and Standard Motor Products meet SAE specs at a lower price..
Install: DIY or shop?
Difficulty: intermediate. Bay time runs about 60–180 minutes with the right tools. Lifespan you should expect: 100,000+ miles.

Common questions Americans ask about fuel tank pressure sensors
What does a fuel tank pressure sensor do?
It measures the pressure (or vacuum) inside the fuel tank as part of the EVAP system. The PCM uses this data to verify that the EVAP system holds vacuum during a leak test and to detect tank pressure changes.
How much does it cost to replace a fuel tank pressure sensor?
Sensors cost $40-$120. On vehicles where the sensor is on top of the tank, shop labor is $300-$600 because the tank must be lowered. On vehicles where it's accessible through a hatch, labor drops to $80-$150.
What are the symptoms of a bad fuel tank pressure sensor?
Check engine light with P0450, P0451, P0452, or P0453 codes; failed EVAP monitor readiness; sometimes long crank after refueling, and occasionally a slight fuel odor (though that's usually a separate EVAP leak).
Where is the fuel tank pressure sensor located?
On most vehicles it's mounted on top of the fuel tank or integrated into the fuel pump assembly. Some applications mount it on the EVAP canister or fuel filler neck for easier access.
Can I drive with a bad fuel tank pressure sensor?
Yes, the vehicle runs normally. The only consequences are a check engine light, a failed emissions test, and the EVAP system not fully purging vapors as designed. Fix it before your next state emissions inspection.
How do you test a fuel tank pressure sensor?
With a scan tool, monitor the FTP sensor PID at various tank levels. With a multimeter, check for 5V reference, ground, and varying signal voltage as the tank pressure changes. Out-of-range readings indicate a bad sensor.
Will a bad FTP sensor cause poor gas mileage?
Not directly, but if the EVAP purge isn't working properly the engine may run slightly rich during purge events, costing 1-2 MPG. The bigger issue is failing emissions tests.
Is the fuel tank pressure sensor the same as the fuel pressure sensor?
No. The FTP sensor measures tank vapor pressure for EVAP diagnosis; the fuel pressure sensor measures fuel rail pressure for injection control. Different sensors, different locations, different jobs.
Can I clear the check engine light by replacing the FTP sensor?
If the code is FTP-specific (P0450-P0453) and the sensor tests bad, yes. If the codes also include P0455 or P0457, you may have an actual EVAP leak that the new sensor will simply detect again.
