How to replace coolant sensor


Hello and thank you for using Fixya. To replace the coolant sensor in your 2004 Hyundai Santa Fe, follow these steps below:

Find the coolant temperature sensor in the engine block on the driver side of the engine compartment. It is screwed into the block and has a wire lead running to the engine wiring harness. Once you locate the sensor, disconnect the wire lead going to the sensor with an open end box end wrench. Inspect the wire lead for melted insulation and discolored insulation. Either condition will require you to replace the wire lead. Make sure the engine has cooled enough to prevent burn injury. Use the appropriate socket and ratchet or open end box end wrench to loosen the temperature sensor. Turn the ratchet or wrench counter clockwise until the sensor is loose enough to turn by hand. Unscrew the sensor and remove from the engine block.Check the temperature sensor for corrosion and the wire lead for damage. Replace the sensor and reconnect the wire lead. Start the engine and allow it to heat up to operating temperature. The cooling fan should come on automatically as the engine temperature increases.Use a gloved hand to squeeze the input hose for pressure. If pressure exists, it means that the coolant is flowing to maintain the engine operating temperature. Now check your engine temperature sensor or warning light to see if it is reading properly.

My 2001 Santa Fe failed inspection because of OBDII codes U0D00 No DTC Definition Located P0118 Engine Coolant Temperature Circuit High Input Anyone know what needs to be fixed?


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.

I received a P1154 OBD code error. It says


DTC P0131 or P0151
Circuit Description
Heated oxygen sensors (HO2S) are used for fuel control and post catalyst monitoring. Each HO2S compares the oxygen content of the surrounding air with the oxygen content in the exhaust stream. The HO2S must reach operating temperature to provide an accurate voltage signal. Heating elements inside the HO2S minimize the time required for the sensors to reach operating temperature. The powertrain control module (PCM) supplies the HO2S with a reference, or bias, voltage of about 450 mV. When the engine is first started, the PCM operates in Open Loop, ignoring the HO2S voltage signal. Once the HO2S reaches operating temperature and Closed Loop is achieved, the HO2S generates a voltage within a range of 0-1,000 mV that fluctuates above and below bias voltage. High HO2S voltage indicates a rich exhaust stream. Low HO2S voltage indicates a lean exhaust stream. If the PCM detects an HO2S voltage that stays below a specified value, DTC P0131 sets for HO2S bank 1 sensor 1, or DTC P0151 sets for HO2S bank 2 sensor 1.
