It is not unusual for a sensor placed directly in the sun to produce a reading that is higher than "normal".

SOURCE: temperature gauge is inaccurate and check engine

Have you checked the antifreeze level lately? Low antifreeze will cause a temp sensor to give false readings. Does your heater work OK, as in does it blow hot air when heater is on? that is another symptom of low antifreeze.

As far as the check engine light coming off and on, I would bet it is the oxygen sensor that might need to be replaced.

SOURCE: My acurite pool hawk reads

I have it on mine as well. With mine, water got inside the sending unit. I took it apart and dried as best I could and reassembled and ut worked fine until more water got inside. I am now looking for a Tupperware type waterproof container to put the sending unit in and then I'll secure the new enclosure underwater on the exit steps of the pool.

My acurite 00509 has stopped giving me the correct temp reading. I've put another temp gauge next to it and acurite shows 78* and my othergauge shows 72*. Do I need to return it or what ? Thanks


The indoor temperature and humidity and outdoor temperature readings can be calibrated on the display to improve accuracy. Calibration can improve accuracy when sensor placement or environmental factors impact your data accuracy. 1. To access calibration mode, press AND HOLD the "?", "?", and "SET" buttons for at least 5 seconds. 2. Once in calibration mode, the preference you are currently setting will be highlighted on the display. 3. Press the "?" or "?" buttons to calibrate the data value higher or lower from the actual reading. 4. Press the "SET" button to confirm the calibration adjustment. The " " icon will remain illuminated next to calibrated values. 5. The next adjustable data will begin flashing, indicating it is ready to be calibrated. Repeat Steps 1 - 4 to calibrate additional data. The preference set order is as follows: OUTDOOR TEMPERATURE INDOOR TEMPERATURE INDOOR HUMIDITY BAROMETRIC PRESSURE (must be set to MANUAL mode; see page 12) After 20 seconds of inactivity, the display will save the adjustments and exit calibration mode. Note: Calibrations will be erased if the display is reset or if batteries are removed and the power adapter is unplugged.

New owner of AcuRite Model 75075. Outdoor temp (just now installed) is reading 7 degrees higher than actual tempperature. How lond does it take for the indoor & outdoor unit to get in Synch?


Typically the Sensors Sync-Up within 10 to 20 Minutes. However, placement of the Outdoor Sensor is also important. The National Weather Service (NWS) and NOAA measure the Temperature in the Shade, and NOT in the Sun. So be sure that your "Exterior Sensor" is placed in the Shade, under an overhang for example. However, be careful not to place the sensor under an overhang, where there may be a soffit-vent or gable-vent, that is used to vent out warm air from the attic. Even a three (3) season, unheated porch can be warmer than the actual external temperature, due to passive/solar heat captured thru the windows (East/South/West).

Indoor temperature on my 00634 acurite station always reads 3 to 4 degrees high


That is most likely the sensor, call the maker of the device and try and buy the sensor.

Misreading outside temperature sensor on 2001 Audi A4


There are four sensors for ambient tempurature and they work in unison to provide information to the temp reading on the dash, the heater control head ( where to direct air, blending of warm/cold/outside/inside air flapper controls) depending on the ambient temp and the inside air temp sensor located just above the radio as well as the sun sensor on the top of the dash as well as the a/c compressor head.

When you start your car, the body control module takes the readings from all sensors, outside air temp located in front of the radiator, air temp sensor located in the airbox ( senses temp of air being drawn in from the outside into the air box), coolant temp, inside air temp sensor and the sun sensor on top of the dash (this is why it takes a few seconds for the climate control system to begine when you start the car). The intake air sensor is 1st priority, inside air second, coolant third, ambient 4th and sun 5th. For instance, if the sun sensor reads the sun is hot but the interior sensor reads cold, the inside akes priority. The goal is for the system to achieve a tempurature inside the car that matches the selected temp. It uses all of the sensors to set the system up to achieve that goal as quickly as possible.

Example; Its mid afternoon, sunny and 40 degrees outside adn your in stop and go traffic. The intake sensor reads 40 degrees, the outside sensor reads 60 degrees (heat from radiator...engine heat protrudes into cabin) and the sun sensor reads high (sun is strong). The system is set for 72. priority one sensor reads 40, inside sensor reads 65, ambient reads 60= system will blow hot air to the floor out put, dash outlets will lightly flow 65 degree air so the sun doesnt roast you yet your feet are cold(if it blew hot air from all outlets, your upper body would be hot but your legs/feet would be cold). as the interior sensor reaches desired temp, air will be distrubuted through thee dash, defrost and floor with the warmest air coming out the floor and defrost, coolest air out the dash vents. Its a complex system!

The two sensors that will screw the system up the most are the intake and interior sensors. the system will function reasonably well with just those two sensors though it wont blend air temps between outlets if the sun sensor isnt working. If the outside sensor fails, it simply uses the intake sensor, if the intake sensor fails it will rely on the front sensor. However, since the intake takes priority over the outside sensor, if the intake sensor sends incorrect resistance info rather than failing, it will take priority and cause the unit to malfunction such as in your case.

The intake air sensor can be changed from the outside with patience. If it where me, I would pay the two hrs labor and let the dealer do it right.
