I have 30% reading on my '89 560SEL. I know its regarding the coolant temp sensor or wiring. I have replaced sensor, and the resistance values both come to the EZL and ECU, meaning the wiring is ok. But the code still remains.

How do I clear the 30% reading? I have disconnected the ECU, Battery, OVP relay but the I still have the code.
