Try a new gas cap, that is usually the culprit. Around $20 on up for keyed at any part store. And easy to put on.

Engine dies while driving. p0443 code. happens after I get gas.


P0443 Evaporative Control System Purge Control Valve Circuit Malfunction.

It is to do with venting the fuel tank.

It may simply be a loose gas cap.

Code po443


code p0443 refers to EVAP canister purge valve--circuit malfunction===causes --wiring---EVAP canister purge valve--ECM

code p0451 refers to EVAP pressure sensor --range/performance problem===causes --EVAP pressure sensor

code p0135 refers to heated oxygen sensor(HO2S) 1 bank 1 heater control --circuit malfunction===causes --fuse--wiring--HO2S ---ecm

basically the HO2S sensor is not stable and altering the air/fuel mixture settings for the ECM and this is not being helped by a faulty EVAP purge valve and pressure sensor.

This is the generic definition for the code.
Your year and model may be different. Possible causes include a faulty purge control valve or the circuit back to the computer.
