Where is the engine coolant temp. circuit high input located on a 2001 hyundai sonata...code p0441

code P0441 IS Evaporative Emission Control System Incorrect Purge Flow

code P0171 IS P0171 System too Lean (Bank 1

IAT = Intake Air Temperature MAF = Mass Air Flow VAF = Volume Air Flow
The first thing I would do is to check at and around the air filter and air intake tube to make sure there are no connectors unplugged. If none are unplugged you will need to take it to a qualified repair facility to have the codes diagnosed. I would recommend finding a Napa Auto Care Center as they are held to a certain standard to be a certified facility.

Hi,
it wouild appear from your description that the engine coolant sensor is developing values in excess of it's set parameters.

Having said that. I would check the connection to the sensor to ensure there is no high resistance, clean the connection anway, refit it, then have a local auto parts shop re-check the codes for you. If the code read-out remains the same. IIt would indicate a faulty coolant sensor.

Good luck.

More than likely the fan switch in the radiator has failed or the fan itself has failed / is not running, so the water returning from the radiator to the engine is HOT therefore you are seeing the high coolant temp input indication. Check out the operation of your radiator fan.

If the fan circuit is OK then the water temp thermostat may very well be be stuck closed.

Thanks for using FixYa.

lol.......Always be prepared......Yes more then likely it will. Have a very large drain pan under the radiator.

replace the sensor and or check the wiring socket going to the sensor

fix the first code then disconnect the battery. see if other codes come back then repeat

The sensor is located at the radiator. follow the wire from the fan to the plug on the sensor. I hope this helps.

you have over 200 sencors in your car i took mine to bob rorhman hyundai and they fixed for 120.00
