Faulty signal. Intermittent fault Reset the codes and restarted the engine, no engine light. Drove around the neighborhood, again nothing. So I'm guessing faulty signal from MAP sensor. Should I clean it, replace it or do nothing and wait to see if it pops up again. Or could it be something else? Sounds like the turbo wastegate isn't opening when it should, causing higher than normal boost pressure which would cause higher than normal pressure in the intake manifold which would then give you the second code.

Perhaps the boost control valve is shot. Originally Posted by Aviator.

I'm not experiencing your clicking noise or trouble codes though, so I can't offer any advice. After resetting the codes the car now shows up new ones immediately but the check engine light doesn't come on until you switch off and restart, so I guess it's a permanent fault.

Signal too low. Permanent fault So sounds like it is the MAP. Originally Posted by sjonnie. Sounds about right. I am getting P as soon as I switch on the ignition after clearing the code.

Last Online: Jan 21st, Last Online: May 11th, Welcome to the forum. Last Online: Today Don't dispear. Mine has thrown up the same code in the last week. New intercooler next week but I am looking at the turbo boost control valve on the front of the engine.

There as the previous poster shwon, links to this in the Diesel section. There is where I have been looking. It is fixable just patience required.

I'm assuming a E3 bhp as you've mentioned the TGV. Looks like you've already eliminated the engine mounts by isolating the TCV at the air filter box and replaced the TGV behind the starter. Might be worth checking the vac connections at the TGV?

As others have said, work though it systematically and progressively - mine turned out to be a collapsed CAT in a recent new front exhaust section! ECM basically means that there is an imbalance between the measured airflow and calculated requirement, so anything that could lead to this imbalance could potentially throw the code.

Three times in the past 5 months the car suddenly loses power and the message "reduced engine performance" displays. This is at highway speeds mph which is scary in traffic. It doesn't die, but pressing the accelerator does nothing. I have to pull over, turn off the car, turn on ignition, and everything is fine again.

Car has been scanned and 2 codes coming up: turbocharger control valve boost pressure fault, too high and A engine control module internal fault intermittent fault.

When I first saw the S80 for sale on a garage forecourt, I examined it and then asked the salesman for a test drive. Everything was fantastic apart from when driving below 30mph. I noticed a slight wave in power. Well same type of thing here except I was driving and not touching the break pedal. When driving above 30mph, however, everything was smooth and beautiful. I told the garage I was interested in the car, but wouldn't touch it unless they were able to fix the fault.

They agreed and a few days later they called me to say they'd found the fault - two sticky injectors and the intercooler was gone. These faults were fixed by replacing with genuine Volvo parts and I collected the car a few days later.

As soon as I drove it home on the first night, a warning message saying "High Emissions Service Required". I promptly took the car to Volvomax My local independent Volvo garage and Douggie there read the codes - the EGR Valve came back as being at fault and the print out said it was either in the "open" or "closed" position. Douggie reset the codes and cleared the memory. But 3 minutes later, on the way home, the same error message showed up on my dash. Also, a few days later, I noticed that whenever I was accelerating up a hill and the revs went above 3, rpm, the message "Engine service required" appeared on the dash and the engine went into Limp mode and switched the turbo off.

I took all this information back to the sales garage and they replaced the fuel filter, removed and cleaned the EGR valve and fitted a brand new genuine Volvo top mount as I'd noticed the one on the engine was knackered. For the first time since I bought the car, the Emissions message did not come on at all. All sorted and still going perfectly to this day.

However, the problem of driving the car up a hill whilst accelerating is still there.

I took the car back to the sales garage this morning and their mechanic checked all the hoses, intercooler, electrics, etc and advised that we'd have to get the codes read. He tried his code reader, but for some reason it wouldn't read my car. I jumped in the car and drove a few miles to the nearest Volvo dealership - Volvo Motherwell. I sat in an amazing, modern, very stylish waiting room whilst drinking a free hot chocolate and reading the Herald as a gentleman by the name of "Harry" retrieved the fault codes from my car.

After about 5 minutes he said the only code it's showing is Boost pressure control faulty. He explained that the D5's engine mounts are actually pressurised and part of the vacuum system. Just last week, he'd had a S80 in with the same fault - accelerating up a hill, the engine would go into limp mode and replacing the front engine mount had cured it.Welcome Guest Log In Register.

View Member Profile. Dec 11AM. Post 1. I bought a XC90 2. I have only one issue with the car thus far. When I am driving at highway speed and am climbing a hill the car will act as if someone is pressing the accelerator on and off in 1 second intervals, even though I am holding the throttle in a constant position. This problem occurs both with and without the cruise control engaged. This stuttering or surging does not change the rpm of the engine.

There are no other symptoms and I have no stored error codes. In looking through previous posts I am considering the turbo control solenoid- anyone have any ideas? Dec 12PM. Post 2. I turned off the car, then restarted and it was back to normal. Any idea wtf is going on? Jan 3PM. Post 3. This may be what yours is doing.This seems to be an ongoing subject Can't find the real culprit. Here is what I have diagnosed so far: 1 my front engine mounting part or was leaking.

Actually inlet vacuum hose was cracked. I blinded my front mounting. And I feel engine vibration, this is normal as mounting does cure it. Applied vacuum to the hose tha goes from solenoid partmounted to the side of the air cleaner box to front mounting. No leaks! Did a test drive while gauge was attached, I was still getting ECM No leaks after test drive.

There was a leak! Hose was Ok, then it means solenoid was leaking, is it? Did a test drive.

D5 ja ECM-6805 -RATKAISTU-

Car was running like it should, boost was excellent, no more ECM Now I have few questions: 1 Why does engine need this solenoid I bypassed in step 4?

Is it only for engine mountings? Be careful by-passing the solenoid, you may have plumbed it 'safe' i. Can you post up the year model and engine spec of the car? This might help the more technical members to assist.

Car is a V70 2. If I disconnect solenoid the one connected to air cleaner box and join those hoses together then I seem to cured my ECM Sounds like the boost control is a little more complex on the oil burner than the T5. But for reference if you by-pass the turbo control valve on a T5, the ECU can no longer control the boost and will likely moan about it.

If you effectively connect the compressor hose to the actuator then you'll not get boost beyond the actuator spring pressure base boost safe ; and if you connect the compressor hose to the inlet tract you don't have any wastegate control dangerous. Too many variables may cause this error!!! This post issue was cured by replacing intercooler. This problem was solved by replacing turbo governor valve.

This means that turbo control valve TCV connected to air cleaner box is pulsing Ok at idle and there are no leaks. Now, when I disconnect hoses from this TCV and join them together then test drive is a success! This means that vacuum pump is functioning, turbo is functioning, right??? I have read probably all posts related to ECM The valve connected to air cleaner box is not turbo control valve. It only controls vacuum to the engine pads open - vacuum to the pads below appr.

If the fault clears after joining the hoses of the pads solenoid, then most probably is the fault in the solenoid itself - lets atmospheric pressure to the rest of the system when should be airtight closed above rpm.

The pads control solenoid is pretty much standard vacuum solenoid found in lots of the vehicles and is a cheap fix. Thanks a lot! Will give a try. At first I need my engine mounting replaced.

Finally I had time to replace my engine mounting.
