Need some help checking codes on my 88 crx si d16z6 obd1 ry wire jumper harness and obd1 adapter for dizy. The check engine light flashes but can't tell which 1 is the slow blink and which 1 is the fast blink. To me it looks the same also if I were to read i think it blinks code 46 which I dont think is a code. It blinks 4 times and then 6 times then a pause blink then just repeats itself and the blinks look the same trying to post a video just don't no how to on here.
Long flashes are about 1 second, while short flashes are about a tenth of a second. You'll get about 3 seconds in between codes. If you want to upload a video, use Youtube and then use the "youtube2" BBcode button in the reply box to bracket the URL.
Thank u for your help got all the codes fixed except 1 code 6 engine coolant temperature. I replaced it and reset the ecu and code is still coming up any idea why or what else it could b also I took the car out 4 a ride around the block n everything is runing right like temp, oil. Just couldn't go above 4 grand in 1 st or 2nd gear thats all the gears I was able to go thru. But it would cut out at 4 grand not leting me hit vtec. Car runs really smooth until i try to rev or speed up above 4 grand any idea wh. I think the ecu might b tuned that way its a p28 not sure if its stock or tuned..
I would check for continuity from the sensor to the ECU. Make sure there's no wiring issues present. Not going into VTEC is probably because of the CEL. The ECU may be in safe mode.
Hi jfrolang I worked on my rex 2day and changed the code 6 engine coolant temp twice thinking the 1st I got was a defective 1. But after I put the 2nd new sensor in the code still came up and I did reset the ecu also I checked voltage and 0.40 was coming out of the sensor wire. Is that good n do u think it's my luck of getting 2 defective sensors???
Check continuity from pins A12 to the positive +plug end at the sensor and if your multimeter has a beeper it should beep. The ground wire goes to the G101 thermostat ground. Since you have OBD1 I am assuming you have a conversion harness so check it from that as well and trace the lead to the OBD0 plug too.
