Trouble code 83
Do you know what signify the trouble code H83 ?
I have done a Sequence Code Recovery on my 1992 ZR1. I have shorted pin "G" to "A" on ALDL connector for reading Central Control Module troubles codes.
The result displayed on speedometer is:
module 1 => C12
module 4 => H31
module 9 => H83
1.0
H31 means Camshaft Sensor fault.
Do you know what signify the trouble code H83 ?
Thanks.

If you can borrow another ECM and try it. Early on I had simular codes on mine and after replacing the cam sensor I found it to be the ECM. They are around $150 exchange in the US.

Disconnect the D connector from the ECM. Check the voltage on the #3 pin on the connector with the switch on. If you have battery voltage showing that is what you want. After that you need to bump the starter and watch the voltage. If the voltage goes down to near zero you have found the cam timing notch. Past the notch the voltage should go back to battery voltage. This proves the cam sensor is working and the problem lies in the ECM.
