New Fife Owner

Postby Goldeneye » Mon Feb 04, 2008 9:52 pm

HI from a New Owner frae Fife
We bought a 03 Plate Mk2.5 three weeks ago, its a Cerrion Silver
Nevada. We bought it as a weekend/fun car but didn't realise that we would
only have it for the weekends! Since purchasing the car it has gone back
to the (non-Mazda) dealer every Monday. The engine warning light keeps
on coming on! The error codes include P0012,P1345 and P1631. The latter
code is indicating alternator malfunction, a new alternator has been
fitted. The other two codes indicate Camshaft Angle Sensor (i) Bank 1
Timing too late and (ii) No signal from sensor. The dealer has since
fitted a new Crankshaft sensor?? and reckoned this would cure the problem -
When they delivered the car back to me they insisted that they have fixed
the car and no warning light is on. We then drive the car, for in some
instances, only a few hundred yards and hey presto the light is back on.
I have a few observations about the problem. IMO the car is sluggish
to start which is consistent with the CAS error codes and the fuel
economy is not as good as I would expect and one further curious instance in
that when the car is parked uphill the warning light will come on and
stay on but when parked downhill and left with iginition off for a
period of time say 5 to 10 minutes the light will stay off until a steep
hill is encountered. Strange mmmmmmm?? Stll waiting on this week's
outcome - anybody out there got any bright ideas?

Sorry to hear about your very unusual problems and no bright ideas I'm afraid - I'll leave that to the more experienced 5 owners - but welcome from a fellow Fife member anyway :)

Hi there. Sorry to hear you're having grief on you new car.
I just happened to be reading the Mazda workshop manual for a Mk2 (Should be similar to Mk2.5) when I saw your post so I've cribbed the following (note I'm not an expert on this at all). Hopefully it will help you persuade the dealer:

Error codes
P0102 - Mass Airflow Circuit low input
P1345 - No SGC signal
P1631 - Generator output voltage no electricity

All three codes can either be because of faulty components (MAF, Camshaft position sensor and alternator respectively) or an open or short circuit between the sensor(s) and the PCM (Powertrain control module - USA speak for the ECU - engine control unit) - in other words, loose connections!

Since you have all three codes, I'd plump for the latter and the workshop manual details the process to track down the connection problem. Reading the diagnostic processes for each code, the dealer should not have replaced either the camshaft position sensor or the alternator before first checking the continuity of the connections.

Could be you have a faulty PCM connector or harness, maybe some some water ingress, potentially a faulty PCM? :shock:

just check that the engine has not been steam cleaned as this can lead to water /corrosion in the wiring plugs etc and cause poor connections,also follow the wiring looms from these components that kevham has listed and see if they all lead to a connector,unplug it and check it and give all the connections a spray with wd40 and this will shift any water,hope this helps

its unusual to have 3 faulty components all at the same time

Thanks for your thoughts/suggestions. As I said I'm still awaiting this week's outcome from the dealer but it seems like I should get my can of WD on standby. As far as I am aware they didn't steam clean the engine but I think it had been sitting idle for around a couple of months prior to us making the purchase.

Who did you buy it from? Some dealers/garages in Dunfermline just don't have a clue sadly, same as anywhere I guess

Wouldn't like to name names re. the dealer but it wasn't based in Dunfermline. Hope to have the car back by the weekend, hopefully cured and ready to go!

So now for the good news! We got the car back last Thursday (7th) and so far so good. Had a great topless weekend and no engine warning light. I understand that the dealer sub-contracted the car out for repair and a new cam angle sensor has been fitted. Thanks for all your messages
