P0132 and P0138 after SAS delete

[louis_m_c]

I left the sensor connected. I've removed the diode and found it, gasp, shorted therefore directly shorting pins A32 and A37. This is what caused the 132 and 138 codes. Now I'm back to the original 410 code but luckily I didn't damage anything. This week I'll be reattempting with a new diode and I'm going to stick with pins A32 and A37 as outlined in the volvospeed tutorial, I guess.

Hi,

I have a similar problem and I am stuck with it without ideas how to solve this.

I had P0132 after I put the transistor on A32-37 and I removed it. But I still have P0132, I even got P0310 (misfire) and the car is acting strang as when I give more gas, it kinda choke and start to backfire with loud "pow". When I drive slow it's ok but it is like it's giving to much turbo boost, more than required.

I'd need some direction to solve this.

Thanks

p0132 is an oxygen sensor code. Sometimes it shows up when the diode is bad, but otherwise there are many reasons for the car to throw p0132. By far the most common is a vacuum leak.

I would check all the vacuum lines carefully, the combination of misfiring and p0132 sounds more like a vac leak than an SAS problem.

You were right, the vacuum line (-1998 LG 520 mm by the meter (976735) between the top part of the turbo and the TCV) was cracked...
I wonder where I`ll find that a sunday morning...

Thanks!

Any vacuum line of the proper ID will work just fine, doesn't have to be a specialty part.
