Getting a Code 12 Knock Control Sensor signal. Wants to start but won't.

Now I know that's not the code I get for a bad knock sensor, Code 52 or 53...What is it? And what do I need to check to fix it? Thanks again in advance guys!

 

PS got the code answer from here:

http://www.troublecodes.net/Toyota/

Then found another one that says:

RPM SIGNAL-NO SIGNAL TO ECU FROM DISTRIBUTOR ("Ne" OR "G") AFTER ENGINE HAS BEEN CRANKED

--DISTRIBUTOR/CIRCUIT

--STARTERSIGNAL CIRCUIT

--IGNITER/IGNITER CIRCUIT

--ECU

For code 12. Now I'm confused. 3VZE motor on a '91. Motor cranks and wants to start.

 

Never mind guys. Got it nailed down thanks to the second defniition for the trouble code. Ignitor...Coil else is brand new but still getting intermittent spark from the coil.

 

i'm having the same problem right now. my 3vz cranks, but doesn't turn over. i checked to see if there was spark, and nothing. what did you do to remedy this?
