Toyota Rav4 check light on - 2004 Toyota RAV4

The check engine light tells you that the computer has detected a problem. Take your rav4 to your local parts store, most will read the codes for free. The codes pretty much tell you what's wrong.

send for scan DTC CODE first

blown fuse and then poss alt brushes or reg out

Here are two of the most common causes of the check engine light.

Most common, MAF ( mass air flow ), sensor. A faulty MAF prevents the computer from determining the correct fuel/air mix ratio.

Oxygen sensor. ( front and rear, front meaning before the catalytic converter, rear meaning after the catalitic converter. The front measures the fuel/air mix being sent through the catalitic converter, the back measures the emmisions and lets the computer know if any fuel/air mix ratios need to be adjusted. Both of these can trigger the check engine light.

I hope this helps you.

the gizmo checks all five tyres....so check your spare.

You need a scanner to pull out the engine light codes.
Use a shopu manual to aid you with the diagnosis and repair.
The slip indicator and vsc light being on means these systems are not working. Once you pull the codes and do the repair and erase the codes the lights will go off.
There will be a code in there for the misfiring.
Good luck and keep me posted.

The code indicates a leak in the evaporative system. 90% of the time it is a faulty gas cap.

I am having a multiple cylinder misfire on my 2006 Toyota RAV4 with the 3.5L V6. Every cylinder is reporting a mifire. Each cylinder has it's own coil. I highly doubt that all 6 coils went bad at once. Does anyone have any idea what my be causing this?? Is that the problem you two are having?
