- Durable construction - this sensor is made from quality components to ensure reliable performance and a long service life
Nothing kills inspection day faster than an illuminated “Check Engine” light tied to the EVAP system. Codes like P0452 or P0453 often mean your fuel tank pressure sensor has failed, leaving the ECU blind to vapor levels. Keep driving and you risk hard starts, poor MPG, and the headache of failed emissions testing. The Dorman 911-259 Fuel Pressure Sensor promises original-equipment accuracy at a fraction of dealer pricing and slots into dozens of GM, Buick, Chevy, and GMC models. This in-depth review shows whether it really fixes those stubborn EVAP faults—and whether you should grab one before the next parts shortage hits.
Key Features & Benefits
-
OE-Matched Calibration – Dorman reverse-engineers GM’s factory sensor, giving your PCM the precise tank-pressure data it needs to shut off MIL lights and enable the EVAP monitor.
-
Plug-and-Play Fitment – Molded connector and mounting boss match the stock part, so the job takes under ten minutes with basic hand tools—no wire cutting or ECM flashing required.
-
Robust Housing – High-temperature polymer and Viton-equipped port resist fuel vapor corrosion and seasonal temperature swings, extending service life.
-
Optimised for EVAP Testing – Accurate from −11 inHg to +11 psi, covering purge, leak, and small-leak diagnostics without drift.
-
Cost-Effective Reliability – Priced far below dealer inventory yet backed by Dorman’s limited lifetime warranty, offering budget peace of mind.
-
Broad GM Coverage (2003–2014) – Direct replacement on popular platforms such as Silverado 1500/2500, Trailblazer, Tahoe, Suburban, Colorado, Equinox, Impala, Lucerne, and more.
If your EVAP monitor refuses to set and you’re tired of chasing phantom leaks, the Dorman 911-259 Fuel Pressure Sensor is the quickest low-cost fix to restore tank-pressure accuracy.

Why Trust This Review
-
Technical specifications were compared against OE part numbers 16238399, 16255883, 13581558 and their service-information pressure curves.
-
Warranty terms and return data were audited from independent auto-parts wholesalers to confirm real-world defect rates.
-
More than fifty verified-purchase Amazon reviews were analysed for longevity, ease of install, and success at clearing readiness monitors.
-
Cross-reference checks with GM factory service manuals ensured correct torque spec and EVAP monitor reset procedures.
No sponsorships or free samples influenced the findings; conclusions rely solely on open-source documentation and customer-reported performance.
Real-World Social Proof
“Swapped this onto my ’09 Silverado in the driveway—CEL cleared after two start cycles and hasn’t returned in 6 months.”
“Fits perfectly on the charcoal canister bracket, connector clicks tight like OEM.”
“Passed state emissions the next day; couldn’t justify dealer pricing when this did the same job.”
A few owners note that installing the sensor without replacing a cracked purge valve hose can cause repeat codes—highlighting the importance of holistic EVAP inspection.

Common Questions (FAQ)
Q1. Which trouble codes does this sensor typically resolve?
Most commonly P0452 (“Fuel Tank Pressure Sensor Low Voltage”) and P0453 (“Fuel Tank Pressure Sensor High Voltage”). It can also assist in clearing P0440-series EVAP leak codes when the original sensor was inaccurate.
Q2. Do I need to drop the fuel tank for installation?
No. On most trucks and SUVs the sensor sits on top of, or beside, the charcoal canister near the rear axle. Jack stands and a 10 mm socket are usually all that’s required.
Q3. Will I have to clear the code manually?
The MIL often goes off after one or two complete drive cycles once the ECU sees correct pressure readings. You may also clear it instantly with an OBD-II scanner.
Q4. Is it safe to install if I run E85 occasionally?
Short exposures are fine, but prolonged E85 usage can shorten sensor life. Consider an OE-grade ethanol-rated sensor if you run flex-fuel full-time.
Q5. Does it come with a seal or O-ring?
Yes, the sensor is supplied with its molded-in port seal; simply lubricate lightly with clean engine oil before insertion.
Verdict
The Dorman 911-259 delivers dealership-level functionality for everyday GM, Buick, Chevy, and GMC owners who want a simple DIY repair that won’t drain the wallet. With OE-matched calibration, drop-in fitment, and a lifetime warranty, it’s ideally suited to drivers facing stubborn EVAP codes ahead of inspection deadlines. Unless you require ethanol-rated hardware or have a non-listed platform, this sensor is the smart, budget-friendly route to a clean dash and a passed emissions test.
