Slip control and error code 47

Recommended Posts

Hi! my car is finally up and running again however the yellow traction control light keeps flashing and its driving me nuts.... i had the intention of polishing my throttle body so i removed all the sensors (TPS,Subtps,TC acutator/motor) now i cant seem to get it back to stop flashing. i used the TSRM trying to reset the sub TPS etc but i guess with no luck as the light is still flashing, i aslo tried to messure ohm from the motor itself acording to the TSRM but i could not get a readout dunno it says 0,85ohm but my tool only messure to 200ohm as lowest (i should get a 0.x readout imo but i dont)

 

So any ideas that flashing yellow light is killing me...

 

1. INSPECT SUB–THROTTLE ACTUATOR

Using an ohmmeter, measure the resistance between the terminals

(ACM to A and A–, BCM to B and B–).

Resistance:

0.82–0.98 at 20°C (68°F)

If the resistance is not as specified, replace the actuator.

Mine doing the same thing since I took the throttle body off to get it polished, at first it was annoying and I was going to sort it , now I like it this way as the slip control is always off which I prefer.... I always used to forget to turn it off when I wanted to have a play

bump, how did you set the sensors up? i think mine needs resetting after messing with the tps and sub tps trying to sort a high idle, the traction control light flashes all the time now, ive tried adjusting the sub tps a bit but it still flashes
