check engine light

  1. Electrical & Computer Systems
    I got a check engine light for mass air flow sensor. Tried cleaning it but ended up changing it out. The truck ran terrible. Low idle and stalling. The light came back on and the truck started running normally again. Any ideas?

    Engine Light is on. Dealer is telling me that is catalytic converter. I know its BS. I feel gas mileage is higher and truck does not have power. Other than O2 sensors what else could it be? Thanks

It seemed fine after i reset the system by unplugging the negative battery cable for 20 minutes. now all the lights came back on...

    Anyone else had a problem where the check engine light is on and the engine seems to have a significant loss of power? Here are the specifics of my truck: 2010 Tundra, 5.7L, 4x4, Automatic, 38K miles. The only thing that I've done different lately is went to NY and played around with 4-wheel...

    Hi, I am new to the forum. I have a 2004 Tundra Double Cab with the 4.7 V8. A year ago, the trouble code for the front O2 sensors came on and these were replaced. More recently, I am getting a P0430, which is, as I understand it, the passenger side Catalytic Converter system efficiency. My...

    I stopped at Autozone to have my check engine light checked and came up as leak in emission evaporator system. Where do I start with that? It runs great but im wondering if I'll get better performance and mileage if it's fixed.

    My 2007 4.7 Liter Tundra Double Cab is throwing the P0430 Code after 150K miles on the exhaust system. That would be the Bank 02 rear sensor causing the code. I jiggled the wires on that sensor and the check engine light went off. The Check Engine Light has come on a couple of times since...

    Started the truck today and there was the light. After 170,000 miles no complaint here. Im out in the middle of nowhere and there is no way to get it checked. its probably just an 02 sensor. Any guesses? Also does the 07 have a way to check the codes by using the ignition off / on trick? ( some...

    I have a 99 Camry with roughly 140K miles on it. My check engine light was on fer while and I brought it in for inspection. I had a catalytic converter put in, but when they started it up the check engine was still on. Today they are running an EVAP smoke test(?)...what are the possible outcomes...

    My otherwise "perfect!" low-mileage 2008 Tundra, that's never given me a moment's trouble, and that has been gently driven and conscienciously maintained since it was brand new, turned on its "Check Engine" light this morning. I'm really worried, because it's very cold where I'm currently...

    I have a 2001 Toyota Tundra and recently I did a check engine light diagnosic and got the code p0446 Evaporative Emission Control System Vent Control Circuit Malfunction. I was wondering if this could be the Charcoal canister or the vent, and is it possible to repair/clean them myself. ALSO what...

    Question here: 1 month ago, check engine light came on. Not surprised, actually, because the truck had started to run VERY roughly. Service department recommended a full fuel system treatment including changing fuel filter, additives, etc. Tab came to about $300...a little steep, but the...

    I have a 2003 tundra with about 98k miles on it. Just recently my check engine light came on and my air conditioner does not seem to be cold. I was wondering what this might be and I thought I would just go ahead and ask before I put her in the shop. Anyone have any ideas or thoughts as to what...

    I have a 2001 Tundra. It has less than 46,000 miles. I try to take care of it and always get it serviced at the dealer. My second battery (a dealer Truestart battery) died last week. It was about 4 1/2 years old. It was cranking fine one day and after about five days of no driving and some...

    Has any one else had CE light on for code PO419 (faulty secondary air injection valves)? My check engine light has come on for the third time in the 2 months I have owned my 2010 Tundra. Only had it back a week after it came on Thursday again. Last week they replaced air injection valve...

    Hello, fellows! I have '03 Highlander 2.4 4WD. Yesterday I tried to rise up to hill on my HL and make slipping. Front left and rear right wheels had slipped about some seconds. After that "CHECK engine" alarm appeared on panel. Scanner showed P0500 - vehicle speed sensor error. This alarm...

    I have a 1997 Tacoma 4x4 V6 and just recently did the deck plate mod. I used sensor safe silicone to seal the deck plate and installed the whole air box back into my truck after letting the silicone dry for about an hour. When I went to start my truck it didn't sound good so I turned it off then...

    I've posted quite a few times the last month about a persistent problem that seems to be worsening. I feel bad because I feel like I always have a question/problem, but due to limited experience, have very little to offer in terms of solutions. So, it is with a great deal of appreciation that...
