I got code PO 452, PO 443, PO 449 all EMS codes what do I need to replace and how hard to do your self?


The codes only tell the mechanic what to test, not what to replace.
You would need to get the shop manual for your vehicle to have the test instructions for each code.
Code 452 is a problem with the fuel tank pressure sensor circuit, 443 is evap canister purge and 449 is the vent valve circuit.
The evap system and those components would need to be checked out.

Blazer is misfiring only in drive while stopped then runs smoothly when accelerated po codes 452 125 are also coming up what is it


Code P 0125 indicates insufficient coolant temp to enter closed loop operation. Most likely cause is either engine is not warming up (stuck thermostat) or more likely bad coolant temp sensor is making computer think engine is not warm and thus sends excess fuel injector pulse making engine run rich. Very common problem which kills gas mileage and may make car run poorly. Easy part to test or just change.

code P0441 could mean one or more of the following has happened:
  • Bad vacuum switch
  • Broken or damaged EVAP line or canister
  • Open in PCM purge command circuit
  • Open or short in Voltage feed circuit to Purge Solenoid
  • Faulty purge solenoid
  • Restriction in EVAP solenoid, line or canister
  • Corrosion or resistance in purge connector
  • Bad PCM
code 452 is evap system- Could be lose gas cap. If you have got gas recently reset code make sure gas cap clicks. ALSO IN THE FUTURE GIVE US YEAR AND MAKE OF VEHICLE THIS HELPS US NARROW DOWN THING.

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.

Why does reduce engine power light comes on chevy


That is a hard problem to pin point without knowing what codes the computer has stored. It can be any number or sensors or engine problems.

You can go to most auto parts stores and they will pull the codes for you for free.
