Question about 1999 Volvo S80

2 Answers

Turbo Boost sensor A

The vehicle response is fine with some occasional backfiring engine sensation but I think is a matter of time before everything goes wrong. The check engine on, OBII reads turbo super charger boost sensor A circuit / Range Performance.
I have no idea how to start in diagnostic this problem nor some manual to follow in how to repair the problem.
Please advise in this issue. My Volvo is a S80 t6 1999
Thank you all for any helpful information

Hi what was the code (p 0244)sounds like you need to replace the the turbo wastegate valve .sounds to me like its overboosting as if the charge from the turbo gets too hot the engine will misfire thus causing damage to engine ,the waste gate valve is there to prevent over pressurisation

2003 Nissan Terrain 2.7 isn't revving up after starting it, cuts out when left running. Was put on a computer code PO235 showed up what is it? Please advise?


Looks like a boost sensor or part of the circuit is malfunctioning. I think you meant a Nissan Terrano? It could be something as simple as a sensor went bad or a hose came loose, to major turbo or engine damage. I would check to see if any of the intake hoses are not connected or loose first, then go from there. The vehicle's computer knows the ballpark value of the boost pressure, but the sensor is sending no signal (or completely erroneous values), so the computer cuts fuel in order to prevent serious engine damage.

I have a 2003 f250 6.0 turbo it starts ruff and on highway when i get to 70mph and hit a hill it will slow down no matter how gas i give and if i floor it black smoke come out


these trucks are known for the egr cooler failing but I think you have turbo issues. maybe the wastegate is stuck open and not making any boost. check your boost guage (normal amount of boost?) make sure your vacume lines and wiring is atached with no leaks. Any check engine light?

Turbo not kicking in like it should cant find no leaking pipe and turbo seems to be working fine


In general the possible causes could be:
- Boost pressure sensor harness is open or shorted
- Boost pressure sensor circuit poor electrical connection
- Faulty boost pressure sensor
- Faulty Turbo/Super Charger
- Engine over temperature.
- Ignition misfire exceeds the calibrated threshold.
- Faulty Knock sensor (KS)

I would doubt its the turbo as you said it seems to be working just fine (unless the wastegate is stuck open/wastegate seal is cracked). Also if the ignition misfire exceeds the claibrated threshold then I would think you'd hear that in the engine running normally. I would say locate the sensor and replace it?

Hope this helps

Overboost condition


Hello, your car is probaly a variale vane turbo fitted and all you need to do is seperate the VNT part of the turbo, give it a good clean with brake/carb cleaner get rid of the sticky oily residue which makes the vanes stick on turbo causing a overboost fault, a delearship might tell you that your car has been remapped at some time setting the boost RPM at like 14 or 1500 and it should be like 2200 I do not know the specifics on your vehicle but a good auto manual will tell you at which RPM your boost should build. I would have a diagnostic done and see if this is your problem, if so do the above and go back and see if it fixed your overboost problem. If not, you will need your ECU remapped. I hope this fixes your problem!

sounds like a very common problem on turbo vag vehicles,the variable vains are sticking in the turbo,your fault code would have said....turbo boost pressure not reached.....common with v v t turbos,run a good quality fuel cleaner through it ,if that doesnt work then a new turbo is the only cure
