Grand Vitara EGR problem

[chubert001]

Hello
Today I have a problem, car Suzuki Grand Vitara 1.9 DDiS 2007.
An error has occurred P0486 Exhaust Gas Recirculation Sensor B Circuit
EGR and cleaned was about one day but the next day the same. Does anyone EGR pinout to check voltage. Regards

After the cleanup, as time passed until the error again go back?
Or error returned immediately?

Only the other day returned an error. On the same day I rode and everything was all right. What I noticed is that the freeze frames of the temperature was 70 degrees Celsius. And the car just started.
What is the egr B Circuit.

[genius76]

why i asked that this error not rely related to wiring, maybe sometimes

70 it is coolant? that import for egr

[genius76]

is there any symptoms after a cold start and idling or driving?

[chubert001]

Sometimes, but rarely fires worse.
Apart from that, everything ok

A lot of egrs can be cleaned up so they function correctly but there is a position switch which signals back egr valve position to ecu; this potentiometer type switch wears out & wrong signal brings up fault codes of high & low voltage range, even though all is fine. That is why many manufacturers recommend not cleaning & replacement only of egr's

i had somebody here he has buyed a new egr the power is back but the code still remain
