vagonan Posted February 15, 2014 Share Posted February 15, 2014 I recently picked up a 1983 Brat in California and trying to fix diagnostic code 22. According to my factory manual it's a problem with the high altitude sensor but the manual tells me to check instructions included in that kit. Also would like to know the part number of the ECU that should be on a '83 brat with CA emissions. Any information helps. Thanks. Quote Link to comment Share on other sites More sharing options...
briankk Posted February 15, 2014 Share Posted February 15, 2014 Usually, a high altitude kit leans out the fuel mixture with increasing altitude. Not knowing what else to do about that, I'd be inclined to replace the high altitude sensor, and see if the engine feels better. Quote Link to comment Share on other sites More sharing options...
briankk Posted February 15, 2014 Share Posted February 15, 2014 Umm.. an ECU on an '83 Brat? I'd have thought that thing would be carb'd. What engine in there? Quote Link to comment Share on other sites More sharing options...
86BRATMAN Posted February 15, 2014 Share Posted February 15, 2014 Models equipped with the feedback carb had an ecu, I've seen a couple of them in my days around these cars. Notvery ccommon in my neck of the woods. Quote Link to comment Share on other sites More sharing options...
ruparts Posted February 15, 2014 Share Posted February 15, 2014 hi, i have parted out over a dozen ea81 cars( no brats) all 80-84 , " i never saw even one that did not have a ecu " , this is in dallas, tx and i don't know where they all came from originally. i know a couple were cali cars but most were likely central states if not texas , but they "all " had a ecm box under the column, all carburetor OHV 1.8 motors.

vagonan Posted February 16, 2014 Author Share Posted February 16, 2014 Thanks for the information. Hmm... So where exactly is the high altitude sensor and what would it look like? Quote Link to comment Share on other sites More sharing options...
Gloyale Posted February 18, 2014 Share Posted February 18, 2014 (edited) All Cali cars and all 2wds after 81 have the Feedback carb. Which is basically just a set of solenoids that open fully, or partially close the Primary and Secondary air bleeds. Not all ECU models have high altitude kits. Also, not all high altitude models had ECUs The high altitude sensor should be mounted on the drivers side front side of strut tower. Squarish box with a cone on one side and a hose in and out and in Cali model case a 2 wire connector.

vagonan Posted February 27, 2014 Author Share Posted February 27, 2014 Thanks for the info. That high altitude sensor was nowhere to be found. Still investigating for code 22. Quote Link to comment Share on other sites More sharing options...
jono Posted February 27, 2014 Share Posted February 27, 2014 Funny reading this from the southern hemisphere ...none of our EA81's came with an ECU of any kind - just carbs, EGR, then cats and ULP with air injection. Never an O2 sensor Quote Link to comment Share on other sites More sharing options...
