Hi i have 1990 buick lesabre limited and the service engine light is on and im getting 13 different codes i believe there a is a bad censor cause the rest of the codes but i dont know here are the codes...


First thing I would do is reset ALL the codes. Do you have your own code sensor OBD2? A soon as the check engine light comes on, pull over and shut off the car and then re-read the codes.
Let me know what you find.
Good Luck

The check engine light comes on and it dies on occasion. It is intermittent. Had it scanned and was told the only fault was mass air flow sensor. Cleaned the mass air flow sensor, replaced fuel filter and...


Anytime you make a change to any part of the emissions system, its best to disconnect the
battery for a few minutes. If you don't, the computer retains the fault code and it will usually keep
coming back. When all power is lost to the computer, it will do a complete scan when reconnected
and engine started. Try disconnecting the battery for a few minutes then reconnect and see what happens.

What does this error code on my 1998 Tiburon mean? PO103 MAF/VAF circuit high input


Hello oceanbreez
It can mean that the mass air flow sensor is bad or you have a vacum
leak. The sensor is on the air intake tube that runs from the intake
manifold on top of the engine to the air filter housing. Check for any vacum leaks going into and in the area of the sensor, such as the clamps on the intake tube and be sure the air filter housing cover is
on correctly and secure, also check the electrical connections at the
sensor make sure they are clean and tight. Also when checking for a
vacum leak a can of spray gumout can be helpfull, just spray the area
in question, if the engine revs up a little a leak is present. If all this
checks out I would replace the mass air flow sensor. But if the car is
running good you can have the code cleared at any parts store for free
then drive it normaly and see if the code pops again, if the engine light
comes on again refer to the above, if not could be just one of those
things. Hope this helps.

Ok... do you have the maintenance history on this vehicle? Did the 'Check Engine' Light come ON? Whenever the 'CHECK ENGINE' light comes on, the ECU (Engine Control Unit) sets a Diagnostic Trouble Code (DTC). These codes identify the particular engine management system which caused the light to come on. You'll need to use/find an OBDII (On-Board Diagnostic) Scanner to retrieve any code which have been stored in the ECU computer. Afterward, we might be able to help you DIAGNOSE and perhaps eventually fix the problem.

2001 VW Golf 2.0 throwing error codes P0103 & P0172


Vacuum leak somewhere.
Possibly could be the O2 sensor (the one before the cat up front).
I'd search for a vacuum leak since you may have rattled something loose.
