Evaporative Emission Control System Pressure Sensor Low Input indicates a low voltage problem in the Fuel Tank Pressure Sensor (FTPS). What the fuel FTP sensor does is convert fuel tank absolute pressure into electrical signals and inputs the signal to the ECM/PCM, (Computer). First thing to do is make sure the gas cap is good and tightened properly. Then check the vacuum lines and wiring at the FTPS (Location-Fuel Tank) to be sure they are good, clean and tight.

I was told to change the emission sensor located near the catalytic converter. Would that help?

Have 04 mercury grand marquis check engine light is on for code po452 had that fixed and light still on


Well ---PO 452 is still FTP Sensor Circuit Low Voltage Detected
new sensor or not



If the sensor reads less than .22volts with key on /engine off --you get a hard fault (code)


Check Sensor Connector


Sensor with no pressure or vacuum in tank is 2.4 to 2.8 volts
Key On/Eng Off On scan tool PIDS


You just need a shop with a data base & proper test procedure
or a different tech or different dealer.

My Starlet EP-82 with 4A-FE engine, the engine check sensor is keep on...but I've checked the engine is running normally...What's going on??


Once the on board computer has found a problem with the engine. It will store the problem in the computers memory as a ( Diagnostic Trouble Code ) and set the check engine Light. The computer will command the check engine light to come on and stay on at this point untill all repairs are made to the Spacific Diagnostic Trouble Codes. It will retract the check engine light to the off possition once the repairs have been made and the repairs were done correctly, and the codes half to be cleared from the computers memory after repairs are finished. Good Luck and have a good XMASS.

Engine codes po452, po440,po122. electrical problem?


You should have 3 grounds 1 from the battery to the engine one from the engine to the body and then from the engine to the frame. Look for these grounds they look like braided flat wire. I think you also may have a loose plug or a cut in the main harness from the rear of the vehicle. Look along the frame as the harness runs from back to front. Looking at your codes I do not think they are related to your electrical problem. I gave up trying to fix my gear indicator, I had to replace the fuel tank sensor to get my gas gage working right.

Engine light on-trouble code P0452


EVAP fuel tank pressure sensor low output. It sounds like the charcoal -filled canister, it's near the gas tank in a cylinder shape.The canister may have cracks or a hose is leaking around the area and it will give a fault code of PO452. Are you smelling any odors or emission smell from the car?

Codes po452 and po453


both codes point to the fuel tank evap pressure sensor. High and low input faults.
Try clearing the codes first and seeing if they come back

You may have a vacuum leak, cracked or open vacuum line or faulty sensor.

Emmisions codepo442,po446,po452,po453


Hi there,

These codes are for the fuel system the system performs a pressure test when the vehicle reaches a certain speed for a certain period of time, predetermined from the factory. The Gas cap is the most likely suspect.  Disconnecting battery will reset (and delete) all error codes and clear the check engine light, VSC, etc. idiot lights on the dash.

Post further comments if further you have the same problem....

Good Luck!!

Thanks
