    it seams to have reset the error on the dash. This is an on going problem. It will reset then come back on a few hours or days later. the diagnostic done by my mechanic comes up with error code 04433 stating "undocumented error"

    Any ideas on what this error code means?

  • Bill Climatianos Sep 02, 2010

    no change in the cars driveability. However we did change one of the spark plug packs about a week ago. We found out that this was a problem because the diagnostics came up with a misfire on number 2 so the mechanic change the spark plug pack and reset the computer.

    About 1 day later this error 04433 came up and has been there since. Do you think I need to reset the ECD somehow?

Hi.

04433 code does not exist, check if the code is corresponding to one of the numbers listed below.

P0433 Heated Catalyst Efficiency Below Threshold (Bank 2)

Test O2 sensor and replace O2 sensor or Cat converter.

P0443 EVAP Emission Control System Purge Valve Circuit- Electrical Fault in Circuit

Replace the purge valve or repair wiring. Check also fuel tank cap and ensure you did not overfill.

Hi! Please try this. Open the hood and remove the positive battery connector and let it sit for 5mins., to reset the system. Try it and see how it goes. Hope this helps and thank you for using FixYa!

    It says undocumented for an update on the diagnostic is needed to know the error code. Do you have any unusual feeling on the car when driving? or its just the instrumental panel tripping? Any experience of hard starting?

Hi, I have a alfa romeo 156 2.0 jts and I have a misfire and error p1670 fuel pressure signal not detect, the mechanic told me that could be the fuel pressure relay but I can't find it....please any help...


A.fa Romeo 156, and no year stated, now that makes this very hard, huh? for sure its 1996 or newer,
and jts 2002, you do make this hard,, ok. normal on fixya. zero inputs.

if you try to out spart the mech, that takes a book
do you want to fix a complex car book free. FSM free>?
the FSM tells you the possible on that code
and how to isolate each, why guess, do the tests. in the book.
this form is mostly N.American. and we dont have that car.
here. Fiat is trying hard to get them here, with 600 engineers. now.
oops no FSM here, cant look it up, why not join a real ALFA or Fiat forum and get faster answers. (non usa forum)
http://www.alfaowner.com/Forum/alfa-147-156-and-gt/

P1670 Electronic Feedback Signal Not Detected
and means zilch, the EFI is rife with feed back,
a really dumb, name but is common today,. running out of good names. FSM is the CURE !!!!

really you need a book.
or post the above. in the correct section , of above forum
i can't search there due to , no login.

google finds NADA, cept above.
a very hard car to service given this rarity of facts.

Is there chain on alfa 156 2.0 liter?


If you are talking about a timing chain I think the answer could be no. I have a 2003 Spider 2L JTS which is the same engine as the 2003 156. Before that they had the 2L Twinspark and both have timing belts which need to be replace regularly along with the pulleys and idlers. Much earlier twinspark engines have a timing chain. Have a look at www.Alfa 156.net. Cheers. Brian.

My 156 sportswagon is burning fuel badly i put 2 gallons in and only got 31 miles for this i can hear an air leak coming from top of engine would this be a likley cause for such poor fuel consumption it's...


an air leak would weaken the mix of fuel to air so giving you better fuel efficiency but a poor power output.
was my last answer not to your liking, re **** fuel consumption on all fiat/alpha cars.but it is true, ask any owner........14.7 average mpg.......£205 road tax.....(tax it for a year and quadruple its value...)
