My car died on me last night. I called my sister's husband and he pulled me with a cable (illegal here, but didn't wanna pay tow truck). I did the diagnostic today, I have codes 42 and 43. I know 42 is because I removed speedocable.

So 43 is what made my car suddenly shut off last night.. or at least I think so... gonna check some stuff with the multimeter, but I'm no good at this stuff. =(

my car is also blinking 42 and 43.....but only when i start it, and turn it back off and then put the key to on again. It runs fine thou. im guessing 42 is cause my speedo is broken, but what exactly does 43 mean?

code 43 is starter signal, no starter signal

I did read that, but what exactly does it mean? my starter works fine. is it perhaps because i removed the alarm and grounded the start wire? do i even need to fix that?

I am gonna try the diannostics now! I also have done a tune up and helped but did not fix the problem.

ok, i finally figured it out, took me like..10 mins haha so lame its been 3 months.
ok so its a 42...WHICH makes sense, cause my speedometer doesnt work, when i bought the car, the previous owner thought it was a speedo cable..but i guess not.

does anyone know if the sensor is in the transmission or is it behind the dash? what is a good way to test the sensor to make sure?

Did you get the trans. sensor issue straightened out yet? If not, I can help you.

I want to do a diagnostic but I dont know which ports I have to bridge. A pic would be helpful. And also how do you know what code number you getting. For example code 24 will blink 24 times?
