james_60 Posted April 15, 2010 Share Posted April 15, 2010 Hi according to google A/C Clutch Relay Control Circuit Low is the p0646 fault code And P0420 Catalyst System Efficiency Below Threshold Jamie Quote Link to comment Share on other sites More sharing options...
james_60 Posted April 15, 2010 Share Posted April 15, 2010 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 Quote Link to comment Share on other sites More sharing options...
quagsy Posted April 15, 2010 Author Share Posted April 15, 2010 thanks do you know how you can fix that fault? Quote Link to comment Share on other sites More sharing options...
james_60 Posted April 15, 2010 Share Posted April 15, 2010 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.

quagsy Posted April 16, 2010 Author Share Posted April 16, 2010 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.

quagsy Posted April 18, 2010 Author Share Posted April 18, 2010 can anyone give me advice how to fix these faults? Quote Link to comment Share on other sites More sharing options...
stef123 Posted April 18, 2010 Share Posted April 18, 2010 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.

quagsy Posted April 19, 2010 Author Share Posted April 19, 2010 they have been there for a few weeks now but the car is running fine. they came up again once initially being cleared. Quote Link to comment Share on other sites More sharing options...
james_60 Posted April 20, 2010 Share Posted April 20, 2010 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.

Stoney871 Posted September 6, 2020 Share Posted September 6, 2020 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?Sent from my SM-G965F using Tapatalk Quote Link to comment Share on other sites More sharing options...
TomsFocus Posted September 7, 2020 Share Posted September 7, 2020 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! Quote Link to comment Share on other sites More sharing options...
Guy Heaton Posted September 7, 2020 Share Posted September 7, 2020 Ford Party. Superb. Doesn't Mondeo also mean world in some languages? And Kuga in Venezuelan means "sets on fire". 😁 1 Quote Link to comment Share on other sites More sharing options...
