3.6.22

Intake Manifold Runner Position Sensor

- G336- , Checking

General Description
The Engine Control Module - J623- uses the Intake Manifold

Runner Position Sensor - G336- signal to calculate a correction

value for the charge air pressure. Evaluation of the signal gives

consideration to the influence of temperature on the density of the

charge air. Failure In the event of signal failure, the Engine Control

Module - J623- employs a fixed, substitute value for calculation

purposes. This may lead to reduced engine output.
Special tools and workshop equipment required
♦ Multimeter.
♦ Wiring Diagram.
♦ Scan Tool.
Test requirements
• Fuses OK.
• Battery voltage OK.
• Switch OFF all electrical and electronic accessories.
• Vehicles with Auto. Transmission, ensure Selector Lever po‐

sition is in “P”.

• Vehicles with Man. Transmission, ensure Shifter Lever posi‐

tion is in “N” with Parking Brake applied.
