When does a fuel pressure sensor go bad?

When you step on the gas pedal and the vehicle does not accelerate like it’s supposed to, then you could have a bad fuel pressure sensor. The engine control unit is not able to transmit the signal properly to the fuel system because it gets inaccurate information from the sensor.

What do you need to know about exhaust gas temperature sensors?

Here the basic substances, for example, yttrium oxide, are used in order to ensure the possibility of use at over 900°C. The individual sensor elements are round, less than 1 mm thick, and with a diameter of less than 2 millimeters. These are provided with two drill holes through which the two platinum rods are guided.

What do you need to know about PT100 temperature sensors?

The Pt100 temperature sensors are very common sensors in the process industry. This blog post discusses many useful and practical things to know about the Pt100 sensors. There’s information on RTD and PRT sensors, different Pt100 mechanical structures, temperature-resistance relationship, temperature coefficients, accuracy classes and on many more.

How is the temperature measured in EGT sensors?

In thermocouples, the other major class of EGT sensors, the temperature measurement is based on the Seeback effect where a voltage is generated across the junction of two conductors of different metals in the presence of a temperature gradient. Different types of thermocouples exist, depending on the combination of metals that is used.

How is the fuel tank pressure sensor connected?

The 3 wire fuel tank pressure sensor, is connected to the fuel tank by a hose, and to the ECM. The ECM uses this value to run the EVAP monitor. This sensor has no bearing on how the engine runs. Here are the facts about the fuel tank pressure sensor: 1) The fuel tank pressure sensor is a 0 to 5 volt sensor.

How to change fuel pressure sensor in Cummins Engine?

Some time ago Cummins issued a service bulletin to change the wiring from the old connector and lead that goes to the fuel pressure sensor to a new connector and lead – an upgrade kit was issued for this which included a new connector, three crimp connectors and an instruction sheet.

What happens if caps fuel injector pump fails?

A relatively new injector pump about 6 months old and exchanged under warranty. Internal seal-diaphragm can fail and fuel will pass into the oil, making oil! Not good! Low Fuel flow / Pressure can damage the internal electronics. The excess fuel is used to cool the circuits and then returned to the fuel tank. Rich.

Can a faulty pressure sensor make the engine not start?

Did you know that a faulty HVAC or air conditioning high pressure sensor can make the engine not start? It so happens that on some vehicles (Cadillacs) the high pressure sensor is connected to the other sensor voltage reference line. So a shorted sensor will render the crank sensor inoperable. Get the scoop here on pressure sensors.
