How to check and replace Camshaft Position Sensor,Coolant Temperature Sensor,Crankshaft Position Sensor,Intake Manifold Temperature Sensor,Knock Sensor,Oxygen Sensor,Vehicle Speed Sensor,Neutral Safety Switch,MAP Sensor and Throttle Position Sensor on Chevrolet Blazer,S10,GMC Jimmy and Sonoma?

Various engine sensors and components have checking procedures,the engine coolant temperature (ECT) sensor is a thermistor that changes resistance with temperature, and a failure in the circuit can cause trouble codes. The resistance should be measured when cold and warm while ensuring reference voltage from PCM is around 5.0 volts for the verification. Manifold Absolute Pressure (MAP) Sensor monitors changes in intake manifold pressure then varies its voltage output accordingly. Look at the reference voltage and signal voltage with the ignition on and engine off, and observe voltage changes as the engine's vacuum changes. Intake Air Temperature (IAT) Sensor acts as a thermistor where you can measure its resistance at different temperatures to make sure it changes as expected. Also, use a scan tool to monitor the IAT sensor for performance. The oxygen sensor in exhaust detects oxygen content which you can check its millivolt signal while warming up your engine. Check whether the oxygen sensor heater has correct voltage or not. Vehicle Speed Sensor (VSS) provides speed data to PCM which can be checked for reference voltage. Depending on the type of engine, Camshaft Sensor and Crankshaft Sensor should be checked for resistance and proper signal output. Finally, Knock Sensors detect engine knock which should be checked for reference voltage and resistance. If any component fails these checks, replacement may be necessary.

Chevrolet S10 Oxygen Sensor

Oxygen Sensor is one of those components in Chevrolet S10 vehicles that are responsible for regulation of oxygen concentration in exhaust gases in order to adjust the setting of the air and fuel mixture and reduce emission levels. It produces a voltage signal proportional to the oxygen concentration; the signal is used by the engine control computer to increase or decrease the fuel injector pulse width. This feedback mechanism makes the engine function in a 'closed loop' to improve catalytic converter effectiveness. Some Chevrolet S10 models employ zirconium dioxide oxygen sensors, maybe both the upstream and the downstream sensors. The upstream oxygen sensor gives the information that allows the computers to change the air-fuel mixture while the downstream oxygen sensor checks on the catalytic converter. Some of the newer models may include wideband air fuel ratio sensors, this will be different from the more conventional and restricted band sensors. But all types of fuel injectors are subjected to contamination and degradation over time which in turn results to more emissions and poor fuel economy.

Each OEM Chevrolet S10 Oxygen Sensor we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
