rav4 reset maintenance light
hold trip A in with engine and key off while holding trip button in turn key and engine on.
keep holding trip button in until light stops flashing when it stops flashing then release the trip reset button this should clear the maintenance warning light. hope this helps
Fist check oil level, the sensor is a pressure switch worked by oil pressure, hopefully the sensor has gone faulty. The oil pressure needs checking, if the oil pump or relief valve has gone faulty, the engine is being starved of lubrication and is causing internal damage. It is advisable NOT to run the engine till the pressure has been checked. (hope it's the sensor)
sun has nothing to do with it but heat may cooling system may not be working 100% hot days may over heat the oil and oil pressure drops,oil pump may be worn you need an accurate temp guage & oil pressure guage and monitor them next time it happens some engines have oil pressure watch dog that kills engine if oil pressure drops
first we will start will the fuel gauge most likely you are correct chevys and 1995 and older jeep wranglers had this problem the sending units failed very commonly. you could have possibly gotton another bad cluster but most likely the speed sensor has worn out. it has a plastic gear being turned by a metal gear and is located near the tail of the transmission. hope this helps
Try this procedure and let me know if this does not work;
Turn the ignition switch to the "On" position but do not start the engine.
1. Press the Trip/Reset button until "Setup Menu Hold Reset" is displayed.
2. Then press and hold down the Trip/Reset button for approximately 2 seconds until "Reset For System Check" is displayed then release the Trip/Reset button.
3. Then immediately press and hold down the Trip/Reset button again for approximately 2 more seconds until "OIL 100% RESET IF NEW" is displayed then release the Trip/Reset button.
4. Then immediately press the Trip/Reset button once to display "HOLD RESET IF NEW OIL" then release the Trip/Reset button.
5. Then immediately press and hold the Trip/Reset button again for approximately 2 seconds until "OIL LIFE SET TO 100%" is displayed.
Turn off the ignition switch, and then start the engine to verify that the reset procedure did work, and you might have to repeat the procedure if the Trip/Reset button is not pushed fast enough, or it is not held down long enough, or it is held down too long during the reset procedure, and it may take a few attempts to be successful.
At this point I would strongly suggest that you have your mechanic hook a mechanical oil pressure guage to the engine and make absolutlely sure that the pressure is up to manufacturers standards. It may simply be a failing oil pressure sending unit, but, until you know, it could turn out a lot more expensive! Thank you, Dana
the first suspect is the igniton switch. when this happens, take the ign key and just barlely turn it, either way, not enough to go off/on just a little tweak, it the lights come back on or flicker, that ign switch will need replacement.
