By blanking it off, will allow you to drive. BUT still flag a relevant DTC for fault.
So, what you are saying here is the fault code will only stop occuring if the actuator is replaced? It is the actuator throwing up this P0489 code all the time? I am going to blank my EGR off on my '56 plate TDCi, I have had the fault light on for 3 years giving me either P0489, or PO490. Anyway, if I replace the actuator with a new one before blanking the EGR, will that stop this stupid blody light harassing me for years on end?
Cheers.
Yes if actuator is faulty replace it & clear DTC's MIL light will then turn off. Although EGR valve actuator for 2006-2013 Connects are not available separately from Ford.
I would advise blanking EGR valves now, Due to new MOT rules pending. Which will prohibit tampering with EGR valves as they form part of emission control systems.
When new MOT rules are implemented - Any EGR valve that has been tampered with e.g blanking plate or has been physically been removed & mapped out of PCM will be an automatic MOT refusal
For starters....
***Diesel emission tests are changing as of 20 MAY 2018. Diesel emissions will be tested against the vehicle manufacturers emission limit***.
Of which manufacturer emission limit is stated on Vin label attached N/S "B" pillar on all Connects
