Question about 1999 Mazda 626

1 Answer

Engine light comes on every 3-4 months: Small Valve Leak Code P___?

Three times in the last year my engine light goes on. Each time I've had it hooked up to the diagnostics machine/computer and the same code appears--P___ (small valve leak). Each time, the car shop could not find anything wrong after a thorough check. This last time the light did not go out--I'm not sure if the code was cleared. The shop suggested I take my car to the Mazda dealer and have it re-flashed. It's about $140.

Looking for a second opinion. The light really bothers me...what happens if something more serious occurs...?

Something may have. if the problem is fixed, the light goes out after a certain amount of start stop cycles. so the original problem looks like has reaccured since it was never repaird eh? did they say what a "small valve leak" means? is the code still the same? if so, i would say there is a small valve leak............lol..........i think discnecting the battery for period of time and reconnecting wil reset the computer. this is probably what the shop does anyway and calls it reflash for 140$.

hope this was helpful...............doug

CHECK GAS CAP / ENGINE SERVICE ARE ON


Most likely an evap system fault code stored in engine computer. Best bet and cheapest thing is go to the dealer and buy a new cap. Install the cap and drive the car for a few days if the light goes off, your all set, if not you need to check for codes. Then probably find a leak or a faulty evap vent valve or purge valve.

Check engine light came on. original code


My guess is you mean misfires, not backfires. How does vehicle run when warmed up? I'm also thinking that the misfire codes are coming from a lean mixture situation. No other codes coming up either? Please reply with year, make, model, and engine, just to confirm heading etc., please.

Check engine light comes on,now is staying on.Code reads P0400.I have been told what the code means but need it narrowed down;I do have a leak in my gas tank on top.Should this be the problem.Just wanted...


the code p0400 is not a fuel leak but a lack of the fuel tank to hold a vaccum. it is possibly one of three things : abad cap :a bad evap solenoid : a bad canister dump valve. most of these would need to be check by a tech to determin which one.
the ets is usualy an abs problem with the lite on it should turn the abs off

Two most common problems for this are the DIC and the fuel pump. Can also be the CPS. First check the code. You can try this first before going to a code reader: 1.With the car already off, switch on the ignition without starting the engine. 2. After approx. 6 seconds, the 'Check Engine' light goes out for an instant before lighting up again for 3 seconds. This 3 second flash is a warning that the actual flashing code is about to start. 3. The flashing code consists of a number of short flashes lasting 0.4 seconds. The 'Check Engine' light goes out for 2 seconds between each new flashing code (if there is more than one fault). 4. After the last flashing code, the 'Check Engine' light goes out for 3 seconds before lighting up again for 3 seconds, after which the flashing codes are repeated. Readout continues in this way as many times as you wish. Number of flashes / Function 2 / Manifold absolute pressure sensor 3 / Temperature sensor, manifold 4 / Temperature sensor, coolant 5 / Throttle position sensor 6 / Oxygen sensor 7 / Adaptation 8 / Purge valve (EVAP valve) 9 / ECM, internal fault If no flashing codes display, the problem is something else (other than those nine listed above) and must be determined using a generic code reader that supports OBD 1, or using the GM/Saab Tech II code reader and programmer. My money is on the DIC as it is a very common failure component and fuel pump failures rarely throw a code. The DICs are good generally to 100,000 to 150,000 miles, but this varies wildly, especially if the car is run with overgapped plugs for any length of time. The plug gap should be 1 mm and no more. Cars that are scrupulously maintained vis-a-vis the plug gapping can see DICs last over 200,000 miles.

Hello There.

These come on as a precousionary measures, even if there is a slight misfire in the engine it generates a code which can be read and inform you why it is there, most of the time these are minor things and light can be reset. The only time you need to get seriously worried is when the letters 'eml' light up with the engine light, then you have a serious problem.

Hope this helps and please don't forget to rate me.

thanks
