Stratus Coupe L4-2.4L VIN G (2003)
Throttle Position Sensor: Testing and Inspection
THROTTLE POSITION SENSOR CHECK
Required Special Tool:
-
MB991348: Test Harness Set
Checking the Terminal Resistance
1. Disconnect the throttle position sensor connector.
2. Measure resistance between the throttle position sensor side connector terminal No.1 and terminal No.4.
Standard value: 3.5 - 6.5 kOhm
3. Measure resistance between the throttle position sensor side connector terminal No.1 and terminal No.3.
Normal condition:
Throttle valve slowly open until
Changes smoothly in proportion to the
fully open from the idle position
opening angle of throttle valve
4. If resistance is outside the standard value, or if it doesn't change smoothly, replace the throttle position sensor.
NOTE: After replacement the throttle position sensor should be adjusted.
Check using oscilloscope
1. Disconnect the throttle position sensor connector and connect the test harness special too (MB991348) in between. (All terminals should be
connected.)
2. Connect the oscilloscope probe to the throttle position sensor side connector terminal No. 3.
