SOURCE: 03 Mazda 6: Check engine light on, code po174

The oil pressure sensor does not have much to do with the P0174 code so the leak on the gasket is not the cause, usually it is the air mass sensor, or the intake sensor. if you have a leak of oil, this might as well mean that whoever changed the oil did not put the right specs of it and this caused the oil to get through. After some time you will experience that the rpms will reach only certain level and won't go higher. Change oil to the right specs and get the sensor cleaned if not to late or replaced (will be expensive). Gasket change wil be needed as well.

Check engine light keep coming on an nothing is coming up on the machine.I took it to meineke an six codes came up.When they went to run the codes on the machine there was no match.I was told to take it...

Something is wrong, but usually not six failures. Typically one failure causes other items to become out of spec, but not actually be malfunctioning....Yes, you may need another mechanic, or <<shudder>> the dealer.
One option is to have the dealer just diagnose the issue, and get your mechanic to fix the issue.

Hi Team, Good Afternoon. I purchased a 2005 Toyota Corolla 1 month ago (Used Car). As soon as I got the car I got the check Engine light. I took the car to Toyota of Irving and they told me that it was...

Did you buy this from a dealer? if so, you should have taken it back ASAP I dont know why you didnt have the Toyota Dealer fix the car, now your in the middle of a mess, getting 2 shops involved, and the car still has a problem. When you bought the car, whoever you bought it from, knew there was a problem, cleared the code and it took a while for the check engine light to come back on. So now you will just have to pay someont to fix the car. The trans shop told you it needed a converter and solenoid, the problem is still there, so make it their problem. I think you need someone who knows toyota . theres no recall that I know of. Recalls are free, anyhow. . ecm is warranteed 8 years or 80k miles. Have the dealer check it out. Have them Check Bulletin TC008-04 and T-SB-0378-08

Honda VT1 Civic - orange engine light on

I would recommend u have it looked into, but maybe by someone else. It sounds like u had the engine codes read, which is done w /a hand held scan tool. It plugs in to a port under the dash, and reads codes stored on the cars computer. The engine light on indicates an emissions problem. When u bring it in, ask for the codes for your records. U can bring the honda to a parts store, and most will check the codes as a free service, and offer advice on what is wrong. Your 1st mechanic apparently erased the codes w/out fixing the problem(s), that's why the light came on again. Let me know how u make out.

Diagnosis Code PO174

before replacing parts i always like to clear the code and see if it comes back .
there could be a fluke that set the code or poor fuel could also cause this code.
i would continue to drive and see if the code comes back and if it does find a independent garage and get a second opinion. and just play dumb and see what they say.
good luck

Check engine light

Check engine light could be on for many reasons. You never know what is wrong.

You would have to take it to Autozone and ask them to scan it (free). The only problem is that if there are multiple failure, it can only show 1 or 2 error code.

So you may not know if there's MORe problems AFTER you fix the first set of code.

Good Luck.
