code p 0447 refers to evaporative emission (EVAP) system vent control---open circuit ===causes --wiring open circuit--EVAP canister purge valve---ECM
code p 0453 refers to EVAP pressure sensor ---high input===causes --wiring short to positive ---EVAP pressure sensor --ECM
code p0453 refers to evaporative emission (EVAP) pressure sensor-- high out put === causes wiring short to positive--- EVAP pressure sensor--- ECM
I would change the sensor unless you have been messing with the wires.
code p0053 refers to heated oxygen sensor (HOS) bank 1-circiut malfunction===causes --wiring --- HO2S code p0203 refers to injector 3 circuit malfunction==causes---wiring--injector ---ECM code p03030refers to cylinder 3-- misfire detected===causes--engine mechanical fault--wiring---ignition/ fuel system---injector---ECT/MAF sensor---ECM code p0453 refers to Evaporative emissions(EVAP) pressure sensor--high input==causes---wiring short to positive--EVAP sensor---ECM code po203 and po303 both have injector as possible fault but the others you will have to fix separately. I doubt an ECM fault as there would be more problems evident so check that one last as it big dollars.
P0453 means EVAP emission pressure sensor high input. Possible causes: - Faulty Evaporative Emission System (EVAP) Pressure sensor - Evaporative Emission System (EVAP) Pressure sensor harness is open or shorted - Evaporative Emission System (EVAP) Pressure sensor circuit poor electrical connection. Code p0701 means Transmission control system range/performance. Possible causes: - Open or short transmission control system circuit - Poor transmission control system electrical connection - Check powers and grounds to Transmission Control Module (TCM)
P0453 - Evaporative Emission Control System Pressure Sensor High Input Possible causes- Evaporative Emission System (EVAP) Pressure sensor harness is open or shorted - Evaporative Emission System (EVAP) Pressure sensor circuit poor electrical connection - Faulty Evaporative Emission System (EVAP) Pressure sensor - Damaged fuel tank pressure sensor
I just looked the the code up. Code is an EVAP code, Evaporative pressure sensor which is part of the emission system. The ECM is seeing high input reading and this is usually because the sensor harness is disconnected or the senor is defective.
