P0420, P0430 codes. Check engine light came on and I scanned and came up with those codes.

[QUOTE="Vinnie_B, post: 16935373, member: 201678"] P0443 - Evaporative Emission System Purge Control Valve Circuit The PCM monitors the state of the EVAPCP circuit output driver. This DTC sets when the signal moves outside the minimum or maximum limit for the commanded state. Possible causes: [LIST] [*]VPWR circuit open [*]EVAPCP circuit open [*]EVAPCP circuit short to ground [*]EVAPCP circuit short to voltage [*]Damaged EVAP purge valve [*]Damaged PCM [/LIST] To verify normal function, monitor the EVMV PID or EVAPCP PID and the signal voltage (PCM control side). With the valve closed, the EVMV indicates 0 mA (0% duty cycle for EVAPCP) and voltage approximately equal to battery voltage. When the valve is commanded fully open, EVMV indicates 1,000 mA (100% duty cycle for EVAPCP) and a voltage drop of 3 volts minimum is normal. Yea I would get this checked out first [USER=204788]@MustangSteve1965[/USER]. You have low mileage and cant see the CATS going bad so soon. [/QUOTE]
