Volvo c70 2007 D5 limp mode
i have this volvo c70 2007 that enters limp mode when 2 faults code come on.
faults code are:
1600:boost pressure sensor,signal out of permissible range.
1000:atmospheric pressure sensor ,faulty signal.
plz look to attachment to the value of sensors and advice.
Have u checked for any turbo leaks
No not yet,but i will do if u think that i have a turbo leak thanks
What checks have you done? What have you tested?
Hi, when I see the difference between pressures value of the manifold sensor and atmospheric sensor I think that the manifold sensor maybe faulty,but I need to be sure to do order. thanks
What were the engine operating conditions when this scan data was taken? I see you have no boost, but the desired boost is very close to actual, which is very close to BARO
Hi, this scan data is at ignition on and engine idle. But i notice that actual manifold pressure and atmospheric pressure not equal as the ignition is on ,is this normal?! thanks
The Baro & MAP should be very close at KOEO. Here on this side of the pond, ours would be in either "HG, or in PSI. in calculating your readings, the calculations are 1095 HPA = 32.34 HG or 15.88 PSI, 1029 HPA = 30.39 or 14.39 PSI, 1005 HPA = 29.67HG or 14.57 PSI. This is enough different to make me want to go and investigate and make sure something wasn't askew with the MAP sensor.
Can you please give us this data with key on engine off?? That will let us help you.
Looks like the scanner is saying you are creating boost at idle. Do you have a separate map sensor and boost pressure sensor? Can you take vac/p[ressure readings and see if they match the sensors? If you look at the boost pressure and atmospheric sensor with KOEO they should read the same. If not one or both are faulty. Good Luck
