Wells Nissan P0507 Relearn Cam and Crank Sensor location and Testing
http://www.wellsve.com/ This video will locate and test the cam and crank sensor on a 2004 Nissan. It will also demonstrate an alternative method to relearn the idle air control. When a P0507 or a high idle occurs after a throttle body clean, the TSB requires the use of the factory (Consultant II) scan tool to reset idle air control. The reset can also be performed by following the steps in this video, without a scan tool.

Throttle Position Sensor Ajustment for idle control - See How
In the video we show you how to adjust the Nissan Hitachi Throttle Position
Sensor(TPS) on the Nissan Frontier Vg33e(V6) Engine. By using a Multi-Volt
meter we explain all the process to make a proper adjustment to the TPS for
recommended idle speed.

WHAT IS A POTENTIOMETER?.
The throttle position sensor responds to the acceleration pedal movement.
This sensor is a kind of POTENTIOMETER which transforms the throttle
position into output voltage, and emits the voltage signal to the ECM. In
addition, the sensor detect the opening and closing speed of the throttle
valve and feeds the voltage signal to the ECM. Idle position of the
throttle valve is determined by the ECM receiving the signal from the
throttle position sensor. This sensor controls engine such as fuel cut. On
the other hand, the "Wide Open and Close Throttle position switch", Which
is build into the throttle position sensor unit, is not used for engine
DTC(code) P01231 is Throttle Position Sensor circuit range/performance
problem - (A) A High voltage from the sensor is send to ECM under light
load driving condition - Possible cause is Harness or Connector(TP) sensor
circuit is open or shorted, or TPS, or Fuel injector, or Camshaft position
sensor, or Mass air flow sensor.
DTC(code) - P0121 is Throttle position sensor circuit range/performance
problem - (B) A low voltage from the sensor is sent to ECM under Heavy load
driving condition - Possible cause is Harness or connector(The Throttle
Position sensor circuit is open or shorted.), or Intake air leak, or
Throttle Position sensor.
How To Check Crank Shaft Position Sensor
I accidently damaged the Ckp sensor on the Hyundai when changing the timing
belt. I take full responsibility, and show how to make sure the wiring is
good and sensor is at fault.
