Engine light likes to come on... sometimes

[speed_freak]

I was driving today and after about 10min of driving my engine light came on. I got to my destination about another 10min later with the car just being normal. When i went to leave to come back on i turned the car on and no engine light. Sure enough though about 15min later it comes back on again after driving. Did an error check when i got home and got a code 12, maybe my code 12 means un-normal?

any ideas?

my theory is my car does not like revving for long periods of time, thats partially my fault since i installed 3.9's

Code 12 means normal mate, and it will repeat it self 3 times before it goes on to any "un-normal" codes.

Test it again and let it run through the code 12 3 times and see if it come sup with anything else.

my patience was not a virtue. came up with code 19

Code 19 - Throttle Position Sensor (TPS) stuck

is this a problem? and how do i fix it

[Brett_jjj]

Replace the TPS.I'm not sure they can be fixed.You could try pulling it off and see if theres any gunk built up around in it etc,and try giving it a clean up.Im pretty sure though that these are just a "throw-away and replace" item.

Internally, TPS are just a series of small switches which let the ECU know if youre at idle, full throttle or backing off. When I opened up my Daihatsu Feroza's TPS, the contacts were very thin (1-2mm max) and I could see them becoming jammed if one ever bent/fatigued.

Luckily ours are Bosch, common and easily changed over should replacement be needed.
