Question

I have a 2005 Hyundai Santa Fe 2.7L with 2 codes P0252 and P0452. The only light that comes on is the ABS and TCS

Answer 1

P0252 The Hyundai Santa Fe does not use this code, unless it is P0262 which is cylinder 1 injector circuit high if you have this as a code there at number 1 cylinder the fuel injector is either non operational due to the harness being disconnected or the fuel injector being non operational, As for P0452 This is a evaporative emission system pressure sensor low input, Low input of the FTPS (fuel tank pressure sensor) is non operational

Answer 2

P0452 Hyundai Code - EVAP Emission System Pressure Sensor Low Input
