When does the O2 sensor go above 45 volts?
This is a common and normal reading. When the catalyst is new you may not see the O2 sensor go above .45 volts but as a catalyst ages the sensor will switch more often above the .45 volts until it cannot clean the exhaust anymore.
What is voltage of accelerator pedal position sensor?
Turn the ignition off, disconnect the accelerator pedal position sensor harness connector. Turn the ignition on, measure the voltage between ground and the 5 volt supply circuit in the accelerator pedal position sensor harness connector. Is the voltage between 4.9 and 5.2 volts? Yes, go to step 3.
How is the voltage measured on a VZ sensor?
Your meter is measuring at the sensor. If you use a scanner to view the live data the computer sees, you will see the same voltage right at the computer. Work the accelerator pedal from idle to wide-open-throttle and you’ll see the voltage change from 0.5 to 4.5 volts.
What’s the voltage on the throttle position sensor?
On my throttle position sensor (TPS) I could never rotate it enough to get the voltage within spec (.98 to 1.00 volt). I ended up taking it off and drilling out the metal sleeves that are in the screw holes. This gave me the slack to rotate the sensor sufficiently to get it to .995, right on the money.
What should the voltage be on the O2 sensor?
The sensor voltage should cycle or fluctuate within the 100 mV-900 mV (0.10 to 0.90V) range. Hence, This means the sensor is operating properly. If the (O2) sensor only produces a low or high voltage signal. So, either you have an engine performance issue or the (O2) sensor stopped working.

What should the voltage be between the CMP sensor and the PCM?
With the ignitionONand the engineOFF, measure the voltage between sensor harness connectorVPWRandPWR GNDterminals (refer to the accompanying illustration). If the reading is greater than 10.5 volts, the power circuit to the sensor is okay. With the ignitionOFF, install a break-out box between the CMP sensor and the PCM.
What should the camshaft position sensor be set to?
Disengage the wiring harness connector from the CMP sensor. NOTE: Prior to removing the camshaft position sensor, set the No. 1 cylinder to 10°After Top Dead Center (ATDC) of the compression stroke. Note the position of the sensor’s electrical connection. When installing the sensor, the connection must be in the exact same position.
