Why is my temperature gauge not reading?

Why is my temperature gauge not reading?

The most common cause of faulty temperature readings is a broken coolant temperature sensor (CTS). The part, which is normally located near a vehicle’s thermostat near the base of the radiator (consult your owner’s manual or repair guide) can get gunked up and fail.

How do I fix my temp gauge not working?

Continue Troubleshooting

  • Turn the ignition switch Off.
  • Unplug the sending unit electrical connector and turn the ignition switch On. Whether the engine is warmed up or cool, the gauge should read cold.
  • Ground the sending unit (signal) wire using a jumper wire. Turn the ignition switch On.

How do you reset the temperature gauge?

What you need to do is simply push the car’s AC button all while pushing the recirculate button at the same time. This may be enough to reset the car’s outside temperature sensor.

Is there a fuse for coolant temperature sensor?

There isn’t one per se. There will be a fused wire with voltage to the instrument cluster (your owners manual should indicate which fuse), but the temperature sensor is providing a variable “resistance to ground,” which the temperature gauge in the dash is reflecting.

What sensor controls the temperature gauge?

To troubleshoot your car’s temperature gauge, you need to know how it works. The temperature gauge reading starts out as a reference voltage that is sent to the coolant temperature sensor. This sensor is nothing more than a thermistor — a variable resistor that changes resistance with temperature changes.

Why is my temperature gauge stuck on hot?

Broken Temp Gauge: If the temperature gauge is maxed out but the engine isn’t actually hot, then the problem may be a broken temperature gauge. The needle may be stuck in the hot range (this can happen after overheating the engine), or a stepper gear in the gauge may be damaged.

Why is my car overheats but the temperature gauge normal?

This problem can be due to a low coolant level in the radiator, a faulty thermostat, a bad radiator, a damaged head gasket, a faulty water pump, or it might just be a bad temperature sensor or gauge giving a false reading.

Can I drive with a bad temp sensor?

It is possible to drive a vehicle with a faulty coolant temperature sensor as the management system defaults to a static reading. A vehicle’s coolant sensor is a critical component used by the engine management system. It directly affects, cooling and fueling of the engine and therefore affects how the engine performs.

Why is my car getting hot but not overheating?

If you find that you’ve got a car running hot but not overheating there might be a few reasons: Clogged or damaged radiator. Low coolant level. Damaged water pump or thermostat.

Why does my Saab 9-3 make a knocking noise?

We carry the motor in Valeo, which is the OEM supplier of these motors to Saab. Broken suspension springs are a common problem in new-gen 9-3’s, and are something to keep an eye out for. For whatever reason, the springs snap near the perch, causing a knocking/popping noise.

What are the most common problems with the Ford 9-3ss?

Although this does not affect the drivability of the car, it can be a somewhat annoying problem. The issue is related to a sensor on the fuel pump, which is prone to failure, resulting in a lost signal and an empty fuel reading. The part in question is attached to the fuel pump, but it is available for buying separately . It fits all 9-3ss models.

When did the Saab 9-3 come out?

After the success of the Saab 900 and subsequent growth of the company through the late 90′, our favorite car company came out with a completely new car in 2003, as a continuation of the 9-3 name.

Why does my fuel gauge drop to zero when I drive?

It is fairly common to be driving, and witness your fuel gauge suddenly drop to zero. Although this does not affect the drivability of the car, it can be a somewhat annoying problem. The issue is related to a sensor on the fuel pump, which is prone to failure, resulting in a lost signal and an empty fuel reading.
