ALL the service check codes ... 66 in particular!?

[crazymixedupkid]

Hi from the UK.

Anyone know where I can find ALL the service check codes?

Engine light comes on intermittantly - switch off and start again and it eventually goes away! This only happens once or twice a month (I drive it everyday).

Have used the service check connector and I'm getting code 66 being reported but I can't find this in the 1991 Service manual!

I notice Lud identified codes 71 72 73 etc as misfiring cylinders for someone ... does he/anyone know ALL the codes?

Thanks

Len,

Great link. Thanks.

Paul,

This code tells me you need a new rear (after cat) O2 sensor for your rear cylinder bank. This is the one located by the "Rear Beam" or you may have a wiring/connection problem. I believe you can use a ohm meter to check the resistance of the heater element on the O2 sensor. If it is a good heater, check all connections for loosness and/or corrosion.

The reason you cannot find this in the 1991 service manual is that ODBI only had one O2 sensor per bank. But I think you can use the same troubleshooting procedure to check the heater element in the O2 sensor, regardless of year car.

HTH,
