Just a heads up, the 'diagnostic codes' link mentioned in this thread is missing:
http://www.club323f.com/wp-content/uplo ... neac61.jpgIt would be really handy to have that reference, or something like it, to help with interpreting the codes. If there's someone who has a copy to re-post that would help.
I know this thread is for the V6 but reading the diagnostics is the same on all BA models.
These reference sites:
https://erwinsalarda.com/how-to-read-ma ... d-scanner/https://www.picoauto.com/library/automo ... 5-pin-dlc/are some of the many similar 'how-tos' that indicate how to read the Mazda blink codes.
I've had success with reading blink codes on my BA 1.5
The codes revealed a problem with the oxygen sensor (aka Lambda sensor). Replacing that got me past an MOT emmisions problem (along with new spark plugs)
I used four LEDs in series (couldn't be bothered to find a suitable resistor) and they flashed to tell me I had trouble code P1170:
Oxygen Sensor (O2S)/Heated Oxygen Sensor (HO2S), bank 1 - incorrect signal.
Intake leak, fuel pressure/pump, wiring, O2S/HO2S, Injector(s), ECT Sensor, MAF Sensor, Spark Plugs
You do have to be patient counting the blinks. I took a video and made sure the blink codes had played through a couple of times so I could sit and watch it to check the codes.
Now I'm stumped by a new set of codes. I have four long blinks, which should mean "everything is fine, nothing to see here". But they are followed by six short blinks. Four long then six short could be read as 0-0-0-6 but I can't find anything about a code 0006. If anyone can shed light on this I'd be grateful
