94 camry no spark code 12

[aaronv94le]

I have a camry that died while driving 30mph, and never ran again. I checked the codes code 12 no signal to ecu from ne or g. So I put a rebuilt distributor. I still have the same problem code 12. I have to fix my car soon and i dont have money for an ecu. Can anybody please help me. I dont know how to check for an open circuit or short between my disrtibutor and ecu. any input is EXTREMELY APPRECIATED

Coil pack dead? Gotta be more specific? Car still turns over just no spark?

MY COIL IS BRAND NEW car turns over fine

Manual or A/T, California or not?

Have yo check the timing belt? If the timing belt is broke, it can't turn the distributor, so no signal to ECM and no spark.

N.E.O.

automatic except california, rotor spins timing is perfect there is NO SIGNAL TO ECU FROM DISTRIBUTOR does anyone know why?

You will have to use a meter to check for NE and G signals at the ECM.

N.E.O.

what do i do if there is no signal, because there isnt, and where is the ecu in a 94 camry le 4door

[aaronv94le]

also when i turn on the key the speedometer goes about halfway up about 70 and slowly comes back down, the car has only been siting up about three months

The ECM is behind the glove box, if there is no signal there then you have to trace the wiring to figure where if there is an open.

No sure what is wrong with the speedo, poor connection or wiring maybe?

Beside replacing the distributor, what else have you done? Did you check all the ground connections to make sure that they are clean and tight? What is the general condition of the car? Got any picture?

N.E.O.

Sorry about your bad luck with the car. Did you talk to the used car dealer about the car quit running after 2-3 weeks?

Well, check the stuff like I had suggested, and see how they are and then will see where it goes.

N.E.O.

new echo is right, you'll have to trace open or short circuit in G & Ne signals and the STA circuit. I can only give you my 95's circuit, the 94 may be slightly different so you should get a circuit diagram. On the ECU there is are three connectors, 26 pin, 16 pin, 22 pin. The wiring for G and Ne is on the 26 pin connector. G+/G- is #18yellow/17black, Ne+/Ne- is #4red/5blue. This is from the ECU side so you'll have to match up the wiring harness connectors. The STA circuit gets its signal from the starter. Its purpose is a richer start mixture. This circuit goes to the 22 pin connector #11black/white. I'm not sure if a bad STA circuit will give a no spark or not, but it is part of the Code 12. As for the ECU, if you need yours checked out or fixed here is a great company that will rebuild yours for about $160: http://avproecm.com/index.htm

Behind the glove box, it should have a sticker on it indicating as such.
