toyota rav4 engine management light

[bournes]

I have a Toyota Rav 4 ( 2002 model ) that has had the engine management light come on intermittently. It was diagnosed by Toyota dealer as the Catalytic convertor. I requested they reset the sensors as this was an import from Holland with different measurement criteria.

This solved the problem but ih has now re-occured and over the pars month been permanety on. Replacing a Cat convertor is not cheap at the dealer. Are there any other garages that I can take the car to to get the management system cehccke d plus if its the Cat a cheaper option that the quoted �1000?

My som had the same problem, told it was the Catalictic converter.

He renewed the air filter which was very dirty and never had the problem again.

Worth a try for a few quid.

Hi bournes. The Cat as such is not monitered as such by the on-board-diagnostics on most cars-but if it is faulty, it will show up on an emissions test(MOT)-local garage will do emission test quite cheaply. You need to get a read out of the faults stored in the onboard ECU- computer brain that controls your car- this will give you a fault code indicating whats wrong. Any local garage that has an OBD1 or 2 diagnostic gizmo can do this for you possibly-give them a ring with your car details- if not( your reg is early on in OBD terms) you are back with the Toyota(expensive) dealer!! . good luck.

Sorry bournes- misread your reg year- your car is well into OBD 2 time- and cars of 2002 can have sensors before and after the Cat, to check on some of its functions- you still need the fault code readout to know if its a sensor or the cat at fault- the diagnostic OBD tool will give a live readout of the sensors operating to check them. Good news is as your car is probably fully OBD2 compliant, your chance of a local garage being able to read out your ECU codes is much higher!!
