P0453 2000 Ford F150 Code - Fuel Tank Pressure Sensor Circuit High Voltage Detected
Quick Answer
The Evaporative Emission System (EVAP) control system pressure sensor detects pressure in the purge line. Common causes include Faulty Fuel Tank Pressure Sensor, Fuel Tank Pressure Sensor harness is open or shorted, Fuel Tank Pressure Sensor has poor electrical connection. Severity is Low - monitor the vehicle and repair when practical. The vehicle can usually be driven if no severe symptoms are present, but symptoms should be checked before extended driving.

Frequently Asked Questions about P0453 2000 Ford F150 Code
What does the OBDII code P0453 mean on a 2000 Ford F150?
P0453 indicates that the Powertrain Control Module (PCM) has detected a high voltage signal from the fuel tank pressure sensor, which is part of the EVAP system.
What are the common symptoms of code P0453 in a 2000 Ford F150?
Symptoms may include an illuminated Check Engine Light, issues with EVAP system performance, failed emissions testing, and possibly a noticeable fuel odor.
What causes the P0453 code to appear on a 2000 Ford F150?
Common causes include a faulty fuel tank pressure sensor, damaged or corroded wiring or connectors, or a malfunctioning PCM.
How do I diagnose the P0453 code on my Ford F150?
Start by checking the fuel tank pressure sensor and its wiring for damage or corrosion. Use a multimeter to test the sensor's voltage and compare it to the manufacturer’s specifications.
Can a loose gas cap cause the P0453 code?
No, a loose gas cap typically triggers codes related to EVAP leaks (e.g., P0455 or P0457), not high voltage in the fuel tank pressure sensor circuit.
How can I fix the P0453 code on a 2000 Ford F150?
Repairs may include replacing the fuel tank pressure sensor, repairing or replacing damaged wiring or connectors, or reprogramming or replacing the PCM if necessary.
Is it safe to drive with a P0453 code on my Ford F150?
While it may be safe to drive for short distances, prolonged driving with this code can lead to higher emissions, reduced fuel efficiency, and potential damage to the EVAP system.
How much does it cost to fix a P0453 code on a Ford F150?
The cost varies depending on the repair. Replacing a fuel tank pressure sensor typically costs $150–$300, while wiring repairs or PCM replacement may cost more.
Can I clear the P0453 code without fixing the problem?
You can clear the code using an OBDII scanner, but it will likely return if the underlying issue isn’t resolved.
What tools are needed to troubleshoot the P0453 code?
You’ll need an OBDII scanner, a multimeter for testing voltage, and possibly wiring diagrams for your vehicle to trace electrical issues.

I have a mis on cylinder 5 in my 2000 f150 the code it’s throwing is p0453. Fuel tank pressure sensor. If I change this sensor should this fix my problem?? Tyia
-
Replacing the fuel tank pressure sensor should replace the code P0453 code, but may not repair the engine cylinder misfire. I haven't seen a bad sensor affecting only one cylinder.
-
I'm havin the same code issue but a misfire on 3 different cylinders. Will fixing this solve the misfire on those 3 cylinders?
-
It's unlikely that the replacing the sensor will take care of the cylinder misfire. Sounds like the fuel pressure is too low. I would recommend check the fuel pressure, if possible use high octane and add a fuel additive.
