Multiple CES codes - Cant find them
Had an Autozoner read the comp on my car today. Three codes came up
P0327
P0236
P0237
Im thinking one is the knock sensor and one has something to do with the turbo. The print out from Autozone didnt list anything for a Volvo.
In the state of IL, the car will fail emissions if the CES is on and I need to have the car tested. Can anyone help? I tried Google but no luck.

the 327 are a knock sensor - the other two relate to boost pressure readings.
Your MAP sensor has likely failed. look on the charged air pipe right behind the intercooler - it sits no top - super easy to replace. approx 90 bucks new at the dealer.
Replace it - clear the codes - and see if the 327 repeats.

How can I be sure its the MAP before I spend the 90 bucks though?
And what sensors would be involved with boost pressure readings?
Thanks
