Low Heating Output Nissan President
Summary of the thread
A 2008 Nissan President is experiencing low heating output and an error code, despite adequate coolant levels and no leaks. The issue may stem from a defective water valve or its electrical connection. It is suggested to inspect the cable and plug connection for damage or corrosion, as a faulty connection can disrupt the valve's operation. Testing with a multimeter is recommended, but consulting a qualified workshop is advised to prevent further issues. The problem was resolved by repairing the defective cable connection.

I haven't inspected the cable and plug connection yet. Could a defective connection really cause both the low heating output and the error code? Is there a way to test the connection?

Yes, a defective connection can certainly cause both symptoms. The error code indicates a malfunction within the system monitored by the connection. Inadequate power or a disrupted signal will affect the valve's operation, hence the low heat. Testing the connection requires a multimeter to check for continuity and voltage. Considering your intermediate expertise, I recommend consulting a qualified workshop to avoid further complications.

Appreciate the advice. I brought the Nissan to a workshop based on your suggestion. You were correct; the cable connection to the water valve was defective. The repair cost 95€ Thank you!

It's possible the water valve is defective, but the symptoms also suggest a potential issue with the valve's electrical connection. Have you inspected the cable and plug connection for any signs of damage or corrosion?
