EA81t: "No Reference Pulse"???

Anyone have any idea what this computer code is saying? I was thinking a problem with the electronic ignition? The engine will occasionally misfire under any conditions....

 

ECU isn`t seeing any ignition pulses(rpm signal) from the coil. Normal w/engine off I believe.

I dont know much about the 82s... I'm a 27 guy. Knowing that... Have you taken anything apart recently? Sometimes when I get to working on stuff I forget to plug the distrubiter cable back in. in the 27s the CRANK ANGLE SENSOR is in the distrubiter... I would assume thats what its looking for. The 27s is also optical an if very dirty can malfunction.

My manual says early elec. ign. ea81 didn't have a crank angle sensor..... i havn't got the car here to look at the moment. You are probably right though, as my manual also says only 1984 onwards ea81s had mpfi...... mine's an '83, and it certainly does!
