P0320 Ignition/Distributor Engine Speed Input Circuit Fault: What is it?
The crankshaft (CKP), sensor measures the rotation speed and position of the engine’s crankshaft. The Powertrain Control Module can control ignition timing and fuel delivery with this information. The PCM will store the P0320 code in its memory if the ...
P0153 Oxygen Sensor Circuit Slow Response (Bank 2, Sensor 1) Fault: What is it?
Oxygen sensors measure the amount of oxygen present in exhaust gases. The sensors continuously send this information in the form a voltage to the Powertrain Control Module. This information is used by the Control Module, in conjunction with other data ...
P0133 Oxygen Sensor Circuit Slow Response (Bank 1, Sensor 1) Fault: What is it?
Oxygen sensors measure the amount of oxygen present in exhaust gases. The sensors continuously send this information in the form a voltage to the Powertrain Control Module. This information is used by the Control Module, in conjunction with other data ...
P0402 Exhaust Gas Recirculation ‘A’ Flow Excessive Detected Fault: What is it?
EGR reduces the temperature of combustion in engines to control nitrogen oxide emissions. Nitrogen oxides are produced when the combustion chamber temperature is too high. EGR helps reduce NOx gas emissions. EGR systems can malfunction just like any other system ...
