Nissan Repair Questions? Ask a Mechanic for Answers ASAP
Hello my name is ***** ***** thank you for your question.
What are the exact code numbers your getting please?
Not a problem. I think I can help you with what you got, but I just wanted the codes to be more 100% sure.
What it a engine over temp code? ( not getting into the knock sensor yet )
Ok, first off the Knock Sensor will never turn on the Service Engine Soon light. So when you get a code that does, such as the P0217 code, that is when you find out you have a knock sensor code. These knock sensors are fairly common to go on these trucks with time and age. If your not due for inspection, I would not worry about changing the knock sensor. But if you had to replace it, it's about 5 hours labor and the sensor is around 130 bucks.
As for the Coolant temp sensor code, This could be due to a bad thermostat, low coolant level or a bad fan clutch. If the coolant system had work done recently, it could simply not have been bleed properly.
Do you have any more questions on this?
