anyone know what these two faults are and how they can be fixed?

P0646 and P0420. its for a fiesta finess 53 plate..

Hi

according to google A/C Clutch Relay Control Circuit Low is the p0646 fault code

And P0420 Catalyst System Efficiency Below Threshold

Jamie

Just Thinking. Your car does not have air conditioning as it was not an option on the finesse

So where that code comes from is anyones guess

Jamie

thanks do you know how you can fix that fault?

Hi

To test whether the catylytic converter is working correctly you will need an emmisions test and the car needs to be plugged into a diagnostics machine or code reader.

How well does the car drive.

What lead you to check for fault codes in the first place.

How many miles has the car done and is it serviced according to manufacturers service schedules.

Jamie

my car has only done 40,000 miles. it paed ssed its emmisions test on the mot which only happined a few weeks ago and i got they codes when i had it serviced last week. the car drives well, it just kinda vibarates now and again when stationary. i got it serviced in arnold clark so i'm not sure which way it was serviced.

can anyone give me advice how to fix these faults?

have these 2 codes just appeared or has someone recently read the fault codes from the car out of curiosity?

it could be that these are old codes that were never wiped from the memory...

personally i would clear them and see if they return.

they have been there for a few weeks now but the car is running fine. they came up again once initially being cleared.

Hi

Make sure you have the radio code to hand.

Are you mechanicly minded.

If so

Disconnect the positive terminal from the battery and leave it dis connected for 30mins- 1 hour.

This should remove any fault codes.

Jamie

am not really mechanically minded but i know where the battery is. whats a radio code and why will i need that?

Buen dia

Mismo problema DTC P0481 y P0645

Tengo el mismo problema con los códigos, mi duda es, porque salen si mi auto no cuenta con A / C? ¿es un fiesta ikon 2011, ademas me guistaria me apoyaran con mi duda, tienen códigos que ver con el motoventilador se prende a los 20 segundos en frio?

Translation-

good day
Same problem DTC P0481 and P0645
I have the same problem with the codes, my question is, why do they come out if my car does not have A / C? Is it an ikon 2011 party, also would you guide me, will you support me with my doubt, do you have codes to do with the motor fan it turns on at 20 seconds when cold?

The translator went slightly too far...a 2011 Ford Party... 

A lot of car models sound odd translated to English though...the Vauxhall Track is another one!

Ford Party.  Superb.  Doesn't Mondeo also mean world in some languages?  

And Kuga in Venezuelan means "sets on fire". 😁

Yep, 'monde' means world in French.
