Well obviously you have stuffed something up for the computer to log a fault.

You need to find someone with a diagnostic tool, plug it in, and see what the code that has been logged means.

I would imagine something to do with the MAF or VSV

forgive my ignorance< but would disconnecting the battery the reset the ECU provide a refresh of the thing, maybe it'd say "oh right< air flow seems stock now, fine to go as normal" ... :blink: ...worth a try ?

My guess is you switched the ignition on while the AFM was unplugged...

Open your fuse box in the engine bay, pull out the EFI fuse for 20 secs and put it back in...

Saves the hassle of resetting everything after battery disconnecting ;) ...

That's what I did in the same scenario. Accidentally forgot to plug the MAF sensor back in and it threw not only the 'check engine' light, but the 'Check VSC System' as well. I took the fuse option and didn't loose my clock or my stereo settings.

      1999 Camry Driver's door locking hatch issue

      It's possible that it could be something fouling or dirt build up, dry, or a broken mechanism, so have a look and give the mechanism some lubrication, most likely though, it'll be the actuator. I found one for a good price on Ebay, $25 delivered: Front Door Lock Actuator Right Side For Toyota Camry 1997-2001 | eBay

      Query about the correct rotors for 2006 ACV40 Camry.

      Hi, I'm looking at a set of front rotors for an ACV40 2006, 2.4L Camry. I got a good price on some RDA's at Sparesbox. However both RDA8112 and RDA7686 show as for my car and I'm wondering what the difference is and if there were changes to the rotors during the model production. So does anyone know which rotor is the correct one? Many thanks in advance.

      It's a simple solution though? Already laying down 60k for a RAV4, so what's another 1k on a phone to make everything work seamlessly? 👍

      Your solution is akin to suggesting that switching to a different car manufacturer would resolve the issue. However, not everyone shares the same enthusiasm for using an iPhone as you do.

      Turboed Corolla Overbuilt?

      that engine will be fine, the rods are the main thing to be concerned about. The 2860 is a decent turbo for the 1zz but in this day and age I'd go for a G25-550. The injectors might be on the small side, we run DW1000's. You need a full length injector, the shorter injectors with adaptors like ID1050x dont fit the 1zz head. You don't need an aftermarket intake manifold, if you do go down that path, avoid the CNC innovations unit, it's garbage. Do the boost control with a MAC valve and control it with the aftermarket ECU of your choice, I use Link stuff on most of my builds with the G4x Storm as the minimum. I also wire a fuel pressure sensor and oil pressure sensor to the ECU in my installs. Use a decent intercooler, the better cores (ARE, PWR, Garrett, Vibrant, Plazmaman, Hypertune) work a lot better than the chinese stuff like Aeroflow. a 450x250-300 fits fairly well with custom end tanks to route the cooler pipes through next to the radiator Don't forget about the clutch and gearbox. These days I like the Uniclutch twinplate, Above 300whp you'll want to think about upgrading the 3rd and 4th gears in the box also with the SSC (Hollinger) gear set and install an LSD of your choice. If you're going to give it a hard time, you'll also want an oil cooler. I like the HKS thermostat type sandwich plates and setrab or mocal oil coolers with -10 speedflow fittings/lines (Chinese AN fittings neck down to a lot smaller internal diameter in their bends, not great for flow) You'll also want to think about brakes, Celica or Sportivo front calipers will bolt on with sportivo discs as a starting point. To have somewhere like Tunehouse do the work you'll want to budget somewhere between 20-40K

      Camry Touring 2010 Fuel consumption 15.2L/100km. Normal?

      I did the mathematics myself regarding costs vs benefits for fuel injector cleaner. I have changed from 91ULP to 95PULP and 98PULP. Price difference can be about 13 -20 cents. Compared to 91ULP, Premium quality fuel should have a better quality additive package designed to have superior engine cleaning capabilities so the engine can perform at their best.

      "Fuel injector cleaner is a waste of money" Only if you by the cheap crap if you use LiquMolly a German Product it does work and you won't waste your Money.
