Suggestions what to do:
Check the vacuum lines running to that valve. If they're cracked, the valve won't open and no air will be pumped in to the system regardless of if the pump is working. Be sure to replace the valve at the exhaust manifold. It's usually a failure of that valve that leads to problems at the secondary air pump.

Drivability isn't affected by this malfunction, but you'll need to get it fixed before it's time for your next vehicle inspection.

When you are searching for codes online, type in OBD2Codes

Check engine light on; cat codes read from machine?


Good morning! for the most part O2 sensors are contaminated due to an incorrect fuel/air mixture...They are an effect rather than a cause...symptoms of jerking up hill and not very fast would indicate a defective Throttle Positioning Sensor (TPS) or Manifold Absolute Pressure (MAP) sensor...Here is least expensive fix...Buy a can of DeOxit from radio shack...Remove and spray O2 sensors...This is a NO-Touch cleaner...Reinstall...Using a voltmeter set to read 5 volts...TPS is bolted to the throttle body and has following colored wires...Black, Gray and Dark Blue...with connector in place push two safety pins into the rear of connector on Dark Blue plus lead and Black negative lead...Start engine...At idle meter must read .08 volts...Bump idle to full... Meter must read 4.2 volts...If reading never gets higher than 2 volts...TPS is the problem...see image

High coolant level


thermostat probably sticking.
Autoparts store will scan the computer for you for free.
They will give you the trouble code/s that make the check engine light come on.
You can just google the number they give you if they don't tell you what it is/means.
Should look like P0130 or P1429 and could be more than one trouble code.
The repair should be easy once you have the code because it will tell you what the problem is.

Hi. Does the car run ok, or very rough? If the vehicle runs rough then I suspect a vacuum leak in the brake booster vacuum supply line.

Air bag light came on sudenly on my prius 2009, what could be the problem?


The air bag light is only part of the srs system
You have seat belts,seat sensors,air bags,all sorts
of sensors,so it could be any thing
In most cases you would need factory service manuals,
if you were to diagnose yourself, as abs codes & trouble
charts are not an internet source of info, as with generic
obd codes
You start at a repair shop with professional software to get the
codes,then they have to go into a data base to find trouble
charts to follow.

you can go to www.free auto mechanic.com & find the the trouble code chart for the obd1 & obd2 scan tools. it's a great site, u can even request a section out of any car manual for them to send u. they do take donations, even if its only $3 but u do not have to send it. they will still e-mail the repair info u need. but the trouble code chart is instantly available.
