Turbo Wastegate (cut away) must be adjusted correctly.
A regular maintenance routine for a turbo charged vehicle will ensure proper operation and have less risk of breaking down, as well as damaging components.
8875b50.jpg To help regulate the air intake pressure a device called a waste-gate is designed to release boost at a measured pressure point

SOURCE: diesel turbo with no power at low revs

this tells me that the injector timing is off just a bit or you may have a weak injector all together.

SOURCE: 1996 subaru legacy engine light code 66

It's in 'safe mode'. Fault 66 is a nightmare! Usually caused by the sensors not talking to each other properly or 'disagreeing' with each other. Check all the sensors are pluged in & have good connections. A dirty connection can cause this code to appear. Disconnect the battery & touch the + & - leads together to discharge the system & reset the computer & fault codes

Fault codes P0236 and P0046 keep coming up on my freelander1 td4 2004


P0236 = Possible causes are

1. Boost pressure sensor harness is open or shorted
2. Boost pressure sensor circuit poor electrical connection
3. Faulty boost pressure sensor
4. Faulty Turbo/Super Charger
5. Engine over temperature
6. Ignition misfire exceeds the threshold
7. Faulty Knock sensor (KS)

P0046 = Turbo/Super Charger Boost Control Solenoid Circuit Range/Performance

.... based on this information I would replace the turbo boost control solenoid first.

Fault codes PO 193 FRP -- PO 101 MAF -- PO 380 -- PO a 09dc/dc -- PO 238 TURBO/ super charger-- PO 118 ECT -- PO 283 fuel temp sensor -- U 2023 brake sensor


101,380 and 118. These together is a no start. Take it to a garage. Just a guess, but I would be looking into the wiring. You waited to long to have a problem fixed. One bad part over time will lead to many codes. The PCM is trying to adjust to make the engine run right. Throwing other sensor out of range. Out of range pops a code.

My saab 95 1.9 tid revs fine in neutral when put in drive and pull of there's no power won't go above 3000 ram any ideas


HI Derek.

There are a few possibilities that come to mind.
3K RPM is generally about the break-even point for when Turbo boost would kick in. There is a dump valve on the turbo system that opens up and vents the extra turbo pressure under high-rpm situations where the boost isn't needed - say high but steady speed on a freeway. If the dump valve system is malfunctioning, then that anticipated turbo run-up in power won't happen.

Revving fine when in neutral may not tell you much, other than that the engine can rev. The gating system will (or should) run differently under load - whether climbing a hill or accelerating, this is where you want the turbo boost to give you the extra power. THat's where the exhaust gate should stay shut, or mostly shut, to allow the turbo to force more air into the pistons.

You might want to check whether the APC (Automatic Performance Control) for the turbo has a separate fuse. (The name might be different on your model, I'm remembering from my 80s/90s era Saabs). If the fuse is blown, that could also lead to lame performance, especially as I'd imagine that the system would be built to fail or go to full open if the APC fails or loses power - that'd keep people from having run-away power that they can't manage.

Hoping this helps

code p0045 refers to turbo/super charger boost control solenoid---circuit open causes ==wiring--boost control solenoid
p0046 refers to turbo/ super charger boost control solenoid--circuit range/ performance===causes ---wiring---boost control solenoid ---mechanical fault.
code refers to system voltage --low===causes wiring---poor connection---battery---alternator
it also refers to ECM power relay control--circuit open===causes -wiring --- ECM relay.
looks like 2 boost solenoids and I would ensure that the battery posts and terminals are shiny clean and tight. have a load test done on the battery to check for bad cell and check the alternator drive belt for condition and tension . Have an out put test done by an accredited auto electrician on the alternator

Steam cleaned engine now have po 237 fault code


Hi Carl, Seems you have some condensation in the turbo boost circuit. Have it blown out with compressed air and hope that it clears the fault. The fault code refers to low signal turbo boost control. It's not a good idea to have vehicles with electronic systems steam cleaned. Regards John

I accidentally hit the rev limiter today and now when I get into second gear and beyond my 2003 GTI 1.8T is making a loud hissing noise like it's the blow off Valve. I have now warning lights on and the...


hi sounds like your high revving has accidenetaly pushed off one of the turbo boost pipes or possibly even split a hose causing it to leak boost pressure get a freind to lightly rev the engine
so you can hear where its coming from if youve split the hose you should find it quite quickly with the bonnet up, or if need be get car up on axle stands and listen for it underneath, for a temporary fix and i mean temporarary wrap the split with gaffer tape or duct tape will restore your boost but not if you give it max revs good luck

Audi A6 3.0 tdi Quattro 2005, glow plug light comes on, limp mode


16619 -Engine boost condition - Limit not reached. Check intake hoses/ connections for leaks. Check Turbo charger waste gate regulating valve/ waste gate working correctly. Must move freely when accelerating, won't achieve full boost if waste gate sticking open. Check Turbo impeller turning freely, oil feed pipe for turbo can get blocked causing impeller to seize. Engine compact, not easy to access these components.

Code PO 299


If you are sure that is the right DTC, P0299 is not a generic OBD-II DTC (Data Trouble Code), and it is a manufacturer specific trouble code that is for an under-boost problem, and it would most likely be related to a problem with a turbo-charger.
