Answers :

P1494 code indicates a fault was detected in the LDP (leak detection pump) that is part of the EVAP system. You most likely have a defective pump switch. This area of the emission system can sometimes be very difficult to diagnose, but usually the fault can be corrected by replacing the switch.

I have a 02 civic si, engine is a k20a3, I have a check engine light that comes on when I'm going home up a mountain that I travel on. The trouble code reads manufacturer control air/fuel metering and doesn't let the engine go past 4,000 rpm. I've notice when it's getting ready to come on that I hear a sparking sound coming somewhere from the car before it comes on. Where is the problem causing this so I can get it fixed without spending 90 dollars to have a dianogstic done.

My 1998 vw is getting less mileage per gallon, and my check engine light is on. I scanned it and the code came up that the throttle body control module needs fixed or replaced. Oh yes and the oil light comes on and beeps then shuts off and I haven't gone 3000 miles. So would fixing the throttle body control module fix these problems?


Yes it will!! you have issues with the tps and air flow valve on the throttle body also you may have to use a code tool to reset all that once the unit is replaced to insure proper throttle response and speed controll through the ECM to the new ... 1998 Volkswagen Jetta

My supposing is that possibly the evap temp sender has an issue and is stopping the compressor from coming on. I have also read about controller programing.
