The P0118 code means that the engine control module (ECM) has detected a voltage signal that’s too high from the engine coolant temperature (ECT) sensor (below). In practical terms, the ECM believes ...

How the thermostat regulates engine temperature
Engineers design modern engines to run in a narrow temperature window where power, efficiency, and emissions all line up. The thermostat sits at the center of that control, opening and closing a ...
The excellent linearity of integrated-circuit temperature sensors makes them ideal for direct analog compensation of the thermally induced errors inherent in many circuits. For example, a ...
Virtually every modern car on the road is equipped with bells, whistles, and sensors designed to let you know when even the slightest thing is wrong with your vehicle. While any driver can appreciate ...
The LM57 is a precision ±0.7°C temperature sensor with resistor-programmable temperature switch. This device has dual output and the trip temperature (TTRIP) is programmable by using two external 1% ...

Every engine sensor explained: why they matter
Air fuel ratios, emissions, and others: oxygen (O2) sensor, exhaust gas temperature sensor (EGT), nitrogen oxide sensor (NOx), knock sensor The video illustrates how each sensor communicates with the ...
Most electronic engineers know that a transistor’s base-emitter voltage (V BE) has a temperature coefficient (TC) of about -2 mV/°C. However, for precision temperature sensors, “about” isn’t good ...
