Can i use gm part 55591002 for both sensors?
Can i use gm part 55591002 (radiator coolant sensor) for my water outlet sensor just to check if one is faulty , beacuse i bought the sensor for my water outlet but im not sure which one is faulty , only diffrence between the two sensors is the terminal pins. One has gold and the other has tin ….would it affect me testing the sensor? I have a feeling its a temp sensor becuase my map thermostat dosnt open when it reaches operating temp and its causing my rad cooling fan not to turn on ….and the only way the cooling fan turns on level one is if i turn on the a.c or defroster …..and then af
Experienced mechanics share their insights in answering this question :
Hi there. Sometimes the material of the contact on a sensor can produce a false reading or not correctly connect to the electrical harness; so if your trying to test the sensor to see if it works, and the OEM sensor is made of a different component or designed for a different use, it’s probably not best to try that. I’m not sure if it would negatively impact the ECU, but I have seen stranger things cause communication errors.
How to Identify and Fix Common car Problems ?

Coolant temperature sensors are not universal and vary depending on the make and model of the vehicle. Different manufacturers use different types of coolant temperature sensors, with different electrical connectors, thread sizes, resistance values, and voltage ranges.
The cruze has 3 sensors. Water outlet, thermostat and on the right hand side of the radiator there is another coolant sensor.
The engine coolant temperature sensor is temperature-variable resistor, which usually has a negative temperature coefficient. It is a two-wire thermistor immersed in coolant and measures its temperature.
Temp Sensors
The Coolant Temperature Sensor is used to measure the temperature of the engine coolant. The readings from this sensor are then fed back to the engine control unit (ECU). This data from the sensor is then used to adjust the fuel injection and ignition timing.
There are two temperature sensors in some vehicles, one to send information from the engine system to the control unit and another from the control unit to the dashboard. The device follows the principle of dependence of potential difference in temperature.
The coolant temperature sensor is responsible for monitoring the temperature of the coolant in your car engine. Monitoring of the engine coolant is necessary as the engine`s fuel requirements are higher when it is cold, and lower when the engine is warm.
The engine coolant is overheating if it`s around 240 to 250 degrees. This is a critical light! It means your engine is beginning to overheat.
It is possible to run a car without a temperature sensor, but it is not recommended. The temperature sensor is an important component of a car`s engine management system, as it measures the temperature of the engine coolant and sends a signal to the car`s computer.
Manifold Absolute Pressure (MAP) Sensor
The MAP sensor is mounted in or near the intake manifold. It determines engine load based on Engine Vacuum. Low vacuum can indicate a high load, like driving up a hill. This requires more fuel.
4 volts or less means the coolant is good. Replace the coolant if the reading is higher than . 4 volts. If you think the only job of antifreeze (coolant) is to cool the engine during the summer and prevent freeze-up during the winter, read on.
Some 2011-2014 model year Chevrolet Cruze vehicles and some 2012-2014 Chevrolet Sonic vehicles with the 1.4L engine may have an engine coolant leak from the water pump. The pump may leak from the weep reservoir or from the water pump shaft seal, leading to a drip of coolant onto the engine or onto the ground.
The most common reasons a Chevrolet Cruze is overheating are a coolant leak (water pump, radiator, hose etc.), the radiator fan, or a failed thermostat. Coolant leak (water pump, radiator, hose etc.)
Each application may have a different temperature sensing need. The differences include what is being measured (air, mass, or liquid), where it is being measured (inside or outside), and the range of temperature being measured.
In most cases, there is little to clean and reuse as when a sensor goes out of calibration from wear or mechanical damage, or fails due to heat damage, the only repair is to replace them.
If the coolant temperature sensor malfunctions, it can transmit a false signal to the computer. And the response of the computer may unbalance the timing and fuel calculations. It is also common for a coolant temperature sensor to fail without warning and send permanently cold signals to the computer.
Often, the engine coolant temperature sensor must be replaced at about 100,000 miles. If you don`t properly maintain the engine cooling system, the sensor could fail much earlier.
The coolant temperature sensor (CTS) can be found somewhere near the engine thermostat, which allows it to function optimally. The tip of the CTS is probably located right next to the engine coolant. The sensor works by measuring the temperature that`s being given off by the thermostat and/or the coolant itself.
The Thermocouple As A Temperature Sensor. The Thermocouple is by far the most commonly used type of all the temperature sensor types. Thermocouples are popular due to its simplicity, ease of use and their speed of response to changes in temperature, due mainly to their small size.
There are two temperature sensors in some vehicles, one to send information from the engine system to the control unit and another from the control unit to the dashboard. The device follows the principle of dependence of potential difference in temperature.
The vibrating wire temperature sensor is fully interchangeable; one indicator can read all sensors.
A malfunctioning coolant temperature sensor may send an incorrect “cold” signal to the ECU, tricking it into believing the engine isn`t hot yet. The ECU will then adjust the fuel injection, ignition timing, and variable valve timing, further raising the engine`s temperature and causing it to overheat.

Knock Sensor + Wiring Harness installation cost? Will YourMechanic install parts if I provide them?
ANSWER : Hello. Yes we will install parts that are provided by you but doing so will void our warranty. You will also be charged for the technicians time if the part you provide does not fit properly. After we install the parts if the condition returns we will come back out and inspect the vehicle. If the issue is not related to the service we performed you will be charged an inspection fee but if it is related we would turn that over to our warranty claims department. The harness is something that our parts department can obtain for you when you’re ready to schedule your next appointment. I will ask our customer service department to send you a quote for the knock sensor installation and they should be able to get a price for that harness too. Thank you for choosing YourMechanic!

hello, i have 1997 gmc safari awd. it recently shut down on the highway and wouldnt start. pulled DTC p0108 MAP sensor high voltag
ANSWER : Hi there. P0108 is the code for a problem with the MAP electrical circuit sensor having too high voltage input to the Engine Control Unit (ECU). This means that the voltage input to the ECU is too high and that it is not in the correct range for proper engine operation to work with inputs from the Mass Air Flow Sensor (MAF) and Throttle Position Switch (TPS). In most cases, the code is triggered by a failure of the MAP sensor or the electrical harness connected to the MAP and the ECU. Most mechanics do not consider the electrical harness as a possible source. You should read this article to learn more about this code and the possible solutions.

Check engine light – O2 sensor circuit + speed sensor circuit…
ANSWER : Hi there. O2 sensor low voltage can be caused my a number of things. Mass air flow sensor was only one of them. It can be a bad O2 sensor, coolant temperature sensor, or wiring issue.
What should be done is a proper diagnosis for the Check Engine Light. Using a complete scanner rather than just a code reader gives a technician the opportunity to not only read trouble codes, but to read voltages for individual sensors. While a code reader tells you the relevant system that set the Check Engine Light on, but with a number of possible causes, the full scan tool allows checking of each individual cause. Having a proper diagnosis will help you have this repaired correctly without replacing parts that are not faulty.

O2 sensors changed, but check engine light still showing code after clearing it I checked fuse. Wires are good and used Denso OE.
ANSWER : Depending on what the code was for will determine if the oxygen sensor was to be replaced. If the conditions were for a rich or lean mixture and it said oxygen sensor, then the spark plugs and wires could need replaced if its a rich reading or the fuel injectors could be clogged or not working if its a lean mixture. If the code said that the oxygen sensor was bad, then check the harness and see if there is a break in the wiring or a short to ground in the wiring from the oxygen sensor to the main harness. If you need further assistance with your check engine light being on, then seek out a professional, such as one from Your Mechanic, to help you.

I did replace the heater core and two sensor the crank sensor and camshaft sensor it didn’t work can it be the computer
ANSWER : If the check engine light is on, what kind of codes is the system detecting? Do you have spark at the plugs? If you have spark, does spritzing some starter fluid give you a momentary startup? If so, there is a fuel issue. More symptoms and information on the car’s behavior before and after the parts you replaced would be very helpful. At this point, I would recommend an inspection from YourMechanic.com to diagnose this car starting problem, get an accurate assessment of damage and cost estimate for repairs. YourMechanic.com can dispatch a mobile, professional mechanic to your location to help you get your car up and working again.
