We just bought a used 3500 6.5 Turbo Diesel, and had to replace the PMD right off the bat. This solved our problems for a day or so. Now we've got hesitation so we used the code reader after the engine light came on. The code indicated P0238, which is Turbocharger Boost Sensor Circuit High Voltage. Is there anything we can do or is this a serious problem?

Thanks!

Check for wire chaffing to the boost sensor mounted on the intake manifold.

Check if the connector is plugged in, and the wiring for frayed, broken.

If ok, could be the sensor is failed

I checked the photo reference in the FAQ section to find the location of the sensor, but did not see a pic of it. Is there a photo reference for locating sensors?

Thanks!

Well, we got the new sensor installed and it works just great. No more hesitation or codes. We were having fluctuations in power when idling also before this, and that has stopped too... Amazing what a big difference a little part like that makes..

Thanks
