Dann Posted March 11, 2008 Share Posted March 11, 2008 For the past week I have been getting the engine light popping up on the dash get the big triangle and on the right get a pic of the engine. This does not happen all the time and most of the time it comes on stays on for about 5 miles or so then goes back out other times it does not come on and some times it comes on and stays on. When this light comes on my tick over is lumpy as it drops to about 500rpm then up to 900rpm and back to 500rpm. The light does not affect the drive of the car nor does affect anything other than the tick over. I am think it might be an o2 sensor that is cloged up or just on its way out ? can some one tell me any different or if it is the sensor how much for a new one ? I have a 1996 MK4 supra N/A. few mods HKS exhaust, de-cat, arc induction etc. Many thanks Dann Quote Link to comment Share on other sites More sharing options...
Nic Posted March 11, 2008 Share Posted March 11, 2008 Check to see if there is a fault code logged, see how to guide here: http://mkivsupra.net/vbb/showthread.php?t=35920 I supply new OEM Toyota O2 sensors for £82 each including postage, you will need 2 on an NA.

hoff Posted March 11, 2008 Share Posted March 11, 2008 Brake fluid level sometimes causes the light to come on and off like that also. Quote Link to comment Share on other sites More sharing options...
Dann Posted March 11, 2008 Author Share Posted March 11, 2008 Thanks will check both of these this weekend. The brake fluid level use the same sensor as the engine pic one ? Quote Link to comment Share on other sites More sharing options...
Nic Posted March 11, 2008 Share Posted March 11, 2008 Brake fluid level sometimes causes the light to come on and off like that also. That would light the brake warning light, not the engine warning light Quote Link to comment Share on other sites More sharing options...
