    Engine sputters/loses power
    When car has been running 20+ minutes, the engine sometimes sputters/loses power and the "check engine" light comes on. I've had two sensors replaced but no luck. Any suggestions for what's wrong/how to repair welcome. Thanks.

      I would say it could be a few things. After it dies out can u restart the car immediately, or does the time vary? The crankshaft monitors directional speed and position of the crankshaft and sends that information to the Electronic Control system(ECS). if yr car can stay running that long I would say it's a sensor that uses information that it collects from the engine itself (such as the speed of the crank, position of the cam) and relays that info to control other parts of the works. Like I said, the crankshafts sensor sends the info it collects from monitoring the crank to the engine control system(ECS). The ECS controls idle speed, ignition system, air-fuel mixture and other engine variable. for some reason on start up the crank sensor and cam sensor don't cause problems until the car warms up and is running For a bit. It's a sensor and if u are knowledgeable and resourceful enough to do it yourself you won't burn a hole in yr pocketh

      Check the belt routing - make sure the belt-driven components are aligned and turning.

      Could it be bearings in alternator? Belt and components seem OK

      Reference the second part of the initial response - make sure the belt-driven components are aligned and turning. This means; the alternator, the steering pump, the a/c compressor,etc.

    Why is my check engine light on?
    Check engine light came on driving down highway. No adverse noises or leaks. Car operating normal.

      First step - have the stored fault codes or check engine light scanned - for free - at any local auto parts store; Advance Auto, Auto Zone, NAPA.
      Then, post a reply as 'add answer' with the specific code (numeric value) for more assistance. There may be a fault code stored in the OBD memory which may not be displayed as a check engine light.

      There are literally hundreds of possible fault codes, so having this detail is important to save both time and money (yours) in terms of correcting this issue.

    Had camshaft replaced at dealership, now oil is pouring out of car.
    130,000 miles, check engine light had been going off and on for awhile, took it to dealership and they said the camshaft needed replaced. Turned it in for the repair and then they found the oil control valve was not working and said it most likely caused the issue. ...

      Not sure what is an oil control valve? Is this the specific part the dealership stated they have replaced?
      Jimm
      10/15/2014 Trish
      Here is what I have found online....The engine ECU can command the system to advance or retard the inlet camshaft timing, thereby providing for faster response. The hardware is a camshaft timing oil control valve mounted adjacent to the inlet camshaft gear wheel and a VVT-i controller mechanism built onto the inlet camshaft timing gear. The camshaft timing oil control valve is a spool valve, controlled via a coil and plunger by the engine ECU. It can signal "advance", "hold" or "retard".

      ...when the engine ECU requires a change in inlet timing, it signals the oil control valve to provide oil pressure to either the advance or retard side of the four vane chambers. A locking pin in the controller locks the camshaft timing in the maximum retard position for engine start-up and immediately after start-up (until oil pressure is established) to prevent any knocking noise.

      This is the part they said still needed replacing and then when oil started pouring out, they said it can happen when this part is bad. However, it's never leaked that I have noticed.

      Ok - typically the camshaft oil control valve is replaced at the same time as the camshaft is replaced. Take the vehicle back to the dealership for the correct repairs.

    Car locked up, won't turn over, feels like emergency break is on (light is on, break isnt)
    My car was running, I came back to drive it and the wheel would barely turn. I turned it off then went to turn it on and it wouldn't turn over (power windows, AC, and dash still work). Feels like emergency break is on.

      If the engine will not start (no starter action), then the problem is not brake related. Several possibilities; faulty battery, faulty /loose /corroded battery cable or terminal connection.

    Loss of power while driving and all dashboard lights on.
    I have a stock 2005 Scion xB with approximately 130,000 miles. For the past few months, sporadically, weird electrical things would happen, like hazards would come on and stay on by themselves. This eventually led to the battery dying, so I bought a new one. ...

    When I turn the key to start the car there is a hesitation before it starts.
    I thought it might be the battery but the battery light has not come on. Then I thought maybe it could be a starter problem. I'm sort of dumb when it comes to cars.

      Are you saying there is a starter motor hesitation before it cranks? If so, nothing wrong with your thought process. I'd have to make sure the battery has a full charge, all battery and starter motor connections all clean and tight. Good voltage and ground, not much if any voltage drops across wiring circuits.

      I also thought about your ignition switch and if you have automatic, some type of neutral switch issue? You need to do some testing before replacing parts. Any testing at the starter, make sure tranny is in park or neutral and the parking brake is set.

      Some of the national brand auto stores will test the starter for you, if you take it off and take it to them.

    When I make a left turn I hear what sounds like sloshing water and water comes into passenger compartment. I don't on r
    This first occurred during or just after heavy rains. However - Rain has stopped, water is no longer coming into the passenger compartment, but I still hear the sloshing sound on a left turn. I don't hear this sound on a right turn.

      two possibilities i can think of
      1. water still trapped inside dashboard ducting
      2. heater core has developed a leak

      if your heater core has gone bad it will start to leak coolant into passenger compartment. it is located within dashboard area, sometimes directly in the middle, but usually more on the passenger side. when it leaks, it will drip coolant into cabin area, and you will be able to smell it

    PO441 AND PO455 CODES, NOT THE GAS CAP
    Thank you in advance, I have a 2007 scion tc that just got transported across the country via truck transport, and now after the trip the check engine light came on. The codes read the following, P0455- Evaporative emission control system pressure leak detected- ...

      You need to do a smoke test to find the leak. The most common cause for these two codes is the gas cap but when that does not solve it you may have a leak at the leak detection pump. That is why I say have a smoke test done because I don't want you replacing the LDP (which you could easily do) and get disappointed if it don't solve it.

      By the way, you can build your own smoke machine if you go on YouTube and use search term "DIY smoke machine"

    When changing gears, I can feel my car accelerate, why is this?
    battery light came on 3 times but for less than a minute but battery is not even 2 years old. Also, when I turn on the car, it makes a loud screeching noise but if I turn off the car and then turn it on again, it stops. the noise also starts when I turn on heater ...

    Why does my car die when I turn on the ac??
    2006 scion tc and the car has a new throttle body because the Toyota dealer said it would fix the random stalling that was going on while driving but they were not a 100% that it would fix the stalling when the ac was turned on.

      Did they also replace the IAC(idle air control)valve that is normally bolted to the throttle body??If not I would replace it.Anytime the ac is turned on it creates a additional load on the engine,so this valve allows more air to bypass the throttle body so that the cars idle will raise,compensating for the drag the ac puts on the engine.
