am getting a code 21 what is this

 

coolant temp sensor

JollyGreenMonster.co.uk

 

 

have you checked the coolent level?

 

yes m8 coolant level is fine but it seems to rev up between 1500rpm and 200rpm nearlly stalling when am at traffic lights so ill change the coolant temp sensor see that helps

 

ok i have a question on this subject. i have a my97 t2000 which when i start ignition the engine check light comes on and goes off. (normal i know) but underneth the steering wheel by the green, and yellow diagnostic plugs are 2 black clips (male and female) that looked like they should be plugged together. so i did, whilst there connected my engine check light flashes. i did attempt to count how many times but gave up after 100!! lol

any ideas?

 

if you look a bit closer i think you should have a green and a black do a search and it will tell you how to read fault codes and reset your ecu using the green and black wires comes in handy sometimes
