Diagnostic trouble code P0638 and/or P1682, dislodged pins in H42-2
|
Saab 9-3 (9440) M03 with engine alternative B207E/L/R
Diagnostic trouble code P0638 and/or P1682 can be indicated despite the fault being located elsewhere than indicated by fault diagnosis. Several electronic throttle actuators have been replaced unnecessarily when the fault is dislodged pins in connector H42-2.
For this reason, H42-2 must be checked with regard to dislodged pins before the electronic throttle actuator is replaced. In particular, check the pins which are connected to the accelerator pedal position sensor (pins 13, 14, 17, 18, 19 and 20 in H42-2).
In the case of customer complaint the following procedure must first be carried out.

Detach the clamp and cables. Use test cable with pin size 0.6 x 0.6 mm from kit 86 12 731. Guide test cable pin into connector pin to sense the clamping force of the pins concerned.
Also check that the engagement on the pins is the same depth as other pins in the connector. Poor clamping force and inadequate connector pin engagement depth can cause poor contact.
Also check the male contact so that no pins are bent, dislodged or damaged.
