The Throttle Sensor responds to the accelerator pedal movement. This sensor is a kind of potentiometer which transforms the Throttle Valve position into output voltage, and emits the voltage signal to the ECU. In addition, the sensor detects the opening and closing speed of the Throttle Valve and feeds the voltage signal to the ECU.
In some setups a crank angle sensor can be a voltage generating (inductive) type sensor although in most cases they are a hall effect type sensor, which means they have a supply voltage, an earth as well as a signal wire which goes to the pcm.. but there are hall effect crank angle sensors which only incorporate two wires, a supply voltage of 5 volts and an earth, but the supply voltage wire is also the signal wire. The way this system operates is as follows, the PCM sends out a reference voltage from the PCM of 5 volts to the crank angle sensor, when the sensor comes into contact with one of the teeth on the tone wheel the voltage is earthed, as the tone wheel continues to turn the earth disappears leaving 5 volts of power, the frequency of this occuring (as well as striking number 1 TDC on the tone wheel) is the way the PCM determines engine RPM
Trouble code P0152 means:O2 sensor circuit high voltage (Bank 2 Sensor 1)
EGR Sensor voltage out-of-range , according to my Haynes repair manual
There are several ways to check your mass airflow sensor. You can measure the output voltage of the sensor, measure the hot film frequency of the sensor, or check the self-cleaning circuit. eHow has a great article that elaborates on these steps.
It means your EGR sensor voltage is higher or lower then expected during self check.
Code P1401 means:Differential pressure feedback electronic sensor circuit high voltage
