SOURCE: Audi 80 oil pressure light

i think from memory that the oil pressure switch is at the back of the cylinder head, if its not there it will be located just above the oil filter, these switches are very cheep to buy and can be bought from any good motor factors. You are right to suspect the switch, its the first thing to eliminate before bogging your self down with more complicated and expensive problems.

SOURCE: camshaft sensor

Do you know if the engine timing is correct? If you get the timing a tooth out you very similar issues, has the cambelt been replaced recently - or is it over due??
Another posibility is the cam chain adjuster. This is oil pressure fed and I think controled by a solnoid, it applies a force between the chain that drives the inlet camshaft from the cambelt driven exhaust camshaft. (Making any sense? Let me know if you want me to simplify) This operating correctly advances and retards the valve timing, when faulty it can make it incorrect. Non start is a fault caused, but more often they become very noisey.
The cam chain adjuster is fed oil when the car is started, you can breifly here it before it has reached operating pressure on normal start up, sounds like a diesel knock for a second, then goes, this is normal. If it continues, its more than likely faulty.
Let me know if you want any more info. If the sensor and wiring is good you'll probably have a timing issue.

It could simply be maybe the person changing your oil never reset the light? or you have a oil pressure sensor leaking or not working.
most of the time its someone never reset the oil change light. even before it goes on it goes by mileage, so maybe it didnt go off yet cause you cnahged it a tad early.so noone even tried to reset it.

I guess you could have an oil pressure problem, but thats going the extreme route.. but if nothing else shows that could be a problem.

I hope that you had the proper weight oil installed, at your oil change. If your oil is up to the proper level, and it's rattling ,this is VERY bad. White smoke usually means steam in the exhaust, and that means a blown head gasket. Check your coolant level. I wouldn't drive it anymore......until someone knowledgeable can diagnose it!!!!!

Check the oil pressure wire attached to the gauge usually in the engine compartment. Dirt can interfere with the signal causing a short which will give you the symptoms you describe. Hope this helps

P0017 and p0014 cobalt 2009


So, I hate to be the bearer of bad news but the codes are as follows.

P0017-Crankshaft Position - Camshaft Position Correlation Bank 1 Sensor 'B'
Possible causes
- Mechanical timing fault
- Blocked oil passage
- Low oil level
- Faulty Exhaust ('B') Camshaft Position (CMP) Sensor
- Faulty Crankshaft Position (CKP) Sensor

P0014-Camshaft Position 'B' Timing Over-Advanced or System PerformancePossible causes
- Dirty Oil
- Low engine oil level
- Faulty Exhaust Camshaft Position Actuator Solenoid
- Exhaust Camshaft Position Actuator Solenoid harness is open or shorted
- Exhaust Camshaft Position Actuator Solenoid circuit poor electrical connection
- Faulty Engine Control Module (ECM)
Bank 1

So in short, you can try the oil change if its been a while, always a good practice, however the fact that its throwing both of these codes together, makes me heavily suspect that your car is experiencing the worst of the possible causes, all your symptoms are tell-tale signs of your cars timing being off, meaning a timing belt job is needed. I highly recommend trying your best not to drive that vehicle, if the timing belt grenades on you while your driving, it will cause catastrophic damage to your motor. I cannot stress to you enough to limit your driving. Timing belt jobs as a general rule of thumb, are anywhere from $700-$1000 depending on the shop, anything more and they are ripping you off. I hope this helps, Good Luck!

I experienced twice an orange engine oil pressure warning light and after the car wont move. I switched off the car and after ten minutes it moved. what is the problem


While an electrical fault or a faulty switch could put the light on, it is such an important light it should never be ignored and the reason for it established immediately. As far as the owner is concerned that means lifting the bonnet and checking the oil level and adding more if the level is low. If it isn't low the car should be recovered to a repair shop. Driving further could be very expensive and very inconvenient...

If the oil pressure light has switched on because the oil pressure is low then continuing to drive will soon wreck the crankshaft bearings or cause crankshaft or camshaft seizure. Damage happens so quickly if the oil pressure is lost at motorway speeds the engine is likely to be severely damaged by the time the car is stopped.

I strongly suggest you have the reason for the light switching on established and repaired.

I have a 2002 Audi TT Quattro. Recently my oil warning light started flashing and does not go off. The oil level is fine. Any ideas what could be causing this


Could well be the sensor/sending unit at fault as Dan states.
Could also be the oil has lost some of its viscosity, become thin and not enough pressure for the sensor to work with.
Had a similar problem with a Citroen some years back was advised to drain the oil, flush the engine out with flushing oil (please read the manufacturers instructions closely) fit a new filter and refill. This worked well for me, also cured a smoking problem from the exhaust.

What does this code mean


Does the truck run ok? If so may just be bad sensor .it reads the correlation between cam and crank shafts so timing is correct so the camshaft control the valves and crankshaft controlling the pistons don't hit each other

Can you tell me the location of code reader 1991 capri ?


1991 is pre-OBD2. code readers will not work.
sorry.
however, all is not lost. Many cars have an alternate way of reading codes from the computer.
Toyota has a block under the hood and you short couple wires together and count engine light flashes
Chrysler you can turn the ignition key on and off a few times and count engine light flashes
in your case for GMs from 1982 to 1995
1: find the 12 pin connector under the dash and short the upper two rightmost terminals.
with the ignition "ON" and engine not running. The system will enter the diagnostic mode. In this mode, the computer will display a Code 12, three consecutive times, by flashing the "CHECK ENGINE", "SERVICE ENGINE SOON" or "MALFUNCTION INDICATOR LAMP" or light. A Code 12 consists of one flash, a short pause, then two flashes in rapid succession.
2:. After Code 12 is displayed, any stored trouble codes will be displayed by flashing the "CHECK ENGINE", "SERVICE ENGINE SOON" or "MALFUNCTION INDICATOR LAMP" light. All codes are displayed 3 times each then a code 12 will repeat. In the diagnostic mode, the computer will also energize all computer controlled relays and solenoids.

Passat 2001 with codes P0012,P0340 it runs fine the turbo kicks in no problem I originally found some broken vaccum line and replaced them but the codes still return


P0340 - Camshaft Position Sensor Trouble
Your cam timing timing is off and the sensor is fine. They are very simple sensors...it's just a magnet...and magnets don't go bad. Check the timing. Incorrect allocation means that the camshaft isnt where the computor thinks it should be at any given time. This could be casued by the base engine timing being off by a tooth or by a problem in the camshaft adjuster.


P0012 Camshaft A: Advance Setpoint not Reached
The code P0012 can be set by the following concerns: Faulty cam adjuster, Faulty cam adjuster solenoid, Low oil pressure, Sludged oil passages and Sticky camshaft.

The variable cam timing uses engine oil pressure diverted to the adjuster mechanism by a solenoid duty cycled by the PCM. Low oil pressure or severe oil sludging can affect camshaft timing operation. Always check oil level and condition when camshaft adjustment codes are present.

Using a full function Volkswagen compatible scan tool enter address word 01 (Engine). Function 08 (Read Measuring Value Blocks) and Display Group 091 (Power Enhancement Camshaft Adjustment).

Observe the 4th display field "Active Camshaft Adjustment Angle" With the engine at idle. The 4th display field should read between -3.0 to +6.0 degrees KW if the camshaft is in the normal unadvanced position. Any other reading at idle indicates that the camshaft is shifted from the normal unadvanced position

Accelerate the vehicle from a standstill in 1st gear using wide-open throttle and observe the display in field 4 again. Under heavy acceleration the display should read between +16.0 to +25.0 degrees KW. This indicates that the camshaft has shifted to the full advance position.

If the display in field 4 does not change from the values in test step 2 or if the display changes but does not reach a minimum of +16.0 degrees KW (i.e. between +6.0 and +16.0 degrees KW), the camshaft timing adjuster mechanism is not advancing the camshaft.

Failure to advance the camshaft could be caused by a faulty cam adjuster, a faulty cam adjuster solenoid, low oil pressure, sludged oil passages, or a sticky camshaft.


Hope this helps (remember to rating this free answer and leave ue some testimonial comment)
