Most probably a lambda sensor need to get it checked on a diagnostic to identify which one is faulty

You will have to take it down to a mechanic and have him scan the car. Once the scan is complete it will tell yo what sensor/sensors are causing the light to stay on. If you do not want to do this, you can try disconnecting the battery for at least 30 seconds, even longer if you wish, and let the computer reset itsself. If the light returns after disconnecting the battery you then have to take it down and have it scanned. You might even be able to remove the sensor causing the problem and clean it. Using a brake cleaner is usually a good product as it evaporates fast and doesn't leave a residue.

  • Yes, possibly the water got up around ignition parts or electrical connections that are giving you problems. Have the engine computer scanned for diagnostic trouble codes. If the engine light was on, it should have set a code.

Oil light will only come on when the sensor does not detect oil flow.You may have a circulation issue not allowing oil to return to oil pan quick enough to keep up on motorway. Have valve covers removed and check for build up at oil return ports in top of head(s)

after the vehicle cooled completely and all the oil drained down it showed half full? that would mean it was anywhere from 2 to 2.5 quarts low? unless you mean that it showed halfway up the full / safe area on the dipstick.

the oil light being on usually means low oil or low oil pressure, if the vehicle still doesn't try to start after it is completely cool then you might have a locked up engine or multiple problems, check the oil again now that it has been sitting awhile look for water in the oil also check for oil in the water.

check battery connections again, make sure they are tight, if lights and such work then try to get a jump from someone. even new batteries can go bad

I would definitely be worried about that oil light though.

good luck and I hope this helps.

Peugeot 306 turbo deisel auto diagnostic light coming on. conditions frdidnt know if the freezing conditions could cause


Check that engine oil is atleast a grade of 10W40. If temperature is below 0°C then Standard engine oil mostly a cause of bad circulation.
To find out if its because of engine oil, drive the car (find out an empty motorway) 60MPH for at least 15-20 minute; come back home; turn the engine off: wait 2 minutes and then start again. if still there is check engine light, then the problem is something else.

No power and Smoking Like a *****


White smoke is a sign of antifreeze (coolant) mixing with your motor oil. Check your coolant to see if it is still full. And check your motor oil to see if it is overfull!

Engine knocking on toyota corolla after replacing damaged sump


oil pan and sump damage are very likely to lead to oil distribution problems, this is not temporary, if you hear a knock have it checked by a local mechanic who can verify it for you, it is possible that the engine is damaged internally.

Engine malfunction light came on


As with any check engine light, the only way to find out what the issue is is to have the code read. The dealership can pull the code and let you know what the issue is.
Before considering driving the vehicle to the dealer though, check the obvious: oil level, coolant level, transmission oil level.
If your uneasy, have it towed.
