What is po234 dtc 2002 volvo s80 2.9 turbo? - 2002 Volvo S80

DTC P1014 - B Camshaft Position - Timing Over-Advanced or System Performance (Bank 1).
At engine start-up the control module checks that the camshaft is in the correct position in relation to the crankshaft. Diagnostic trouble code (DTC) ECM-62 is stored if the control module detects the camshaft in an incorrect position on start up.

Possible source:
Camshaft cogs incorrectly seated
Incorrectly installed camshaft pulley
Contact resistance in the terminals.

Condition:
Malfunction indicator lamp (MIL) lit
The engine misfires.



DTC P1237 - Turbo Control Valve
Looks like the turbo is not producing enough boost. Check the waste gate hoses and the waste gate itself to see if its bound up. If the waste gate is working right, I would suspect a bad turbo.

This is an advanced level repair. You may want to have Volvo do the diagnostics on this one. Your code is for low turbo boost pressure. The waste gate is a big silver actuator on the turbo. It has vacuum hoses going to it. See if they are all hooked up. Also see if you can move the lever that the actuator pushes on. If its jammed that may be your problem.


Hope this helps and just keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa.

p0234 is engine over boost condition. According to Volvo P0234 is a turbo control valve. Maybe a wiring issue?
Did you do a hard reset after clearing the code? hope this helps!

much less power, much less speed, and much less mpg, now was that realy worth it?

P0216 - injector timing control circuit

P0234 - turbo / supercharger over boost condition

P0523 - engine oil pressure sensor / switch circuit high inout.

is this a t6? if so yes. turbocharged engines have more horsepower than naturally asprirated engines, a turbo charger works like a supercharger by forcing more air into the intake, while a super charger is usually belt driven a turbocharger is exhaust driven, it will be located in the exhaust pipe or exhaust manifold and is turned by exhaust gases passing thu with the opposite side connected to the air intake pipeing, some have the intake air piped thru a intercooler which is mounted in front of the radiator(cooler air is more horsepower)
type 2002 s80 volvo in your search bar and you can find a ton of info

0237 is turbo/ super boost sensor a circuit malfunction
0236 is turbo/ super boost sensor a ckt range performance

Don't know much about VW but if it's fine, and it doesn't happen again I wouldn't worry about it. If it does try resetting the ECU by removing the battery terminals and touching the positive lead(red wire) to the negative battery post. It might spark a little, this is just the capacitors discharging, resetting your ECU and starting over. It's like restarting your personal computer

how much is the turbo boost part for the 2002 volvo

u try to check gear position switch and may be u can get the DTC is easy to troubleshooting .Thanks

This is what my code scanner says:
P0234 Engine Overboost Condition
If you have a non-turbo model, then it's probably something else. It may be a bad turbo overboost switch. My S80 is non-turbo but I had an overboost switch go out on my Mercedes and it shut down the turbo but I had the same error message. Good luck!
