Engine Controls - Sensor Operating Range Specifications: Introduction: Notes

2003 Nissan-Datsun Sentra SE-R Spec VSECTION Notes

Sensor operating range information can help determine if a sensor is out of calibration. An out-of-calibration sensor may not set a diagnostic trouble code, but it may cause driveability problems.

NOTE: Perform all voltage tests using a Digital Volt-Ohmmeter (DVOM) with a minimum 10-megohm input impedance, unless stated otherwise in test procedure. Using an oscilloscope may provide better test results on some sensors. For oscilloscope waveforms and ECM terminal identification, see PIN VOLTAGE CHARTS article.

  • The engine overheats, stalls repeatedly, or misfires under load.
  • You are missing required tools, torque specs, or safe lifting equipment.
  • You are not confident in the next step or safety outcome.
