Subject:	Check Engine' Light and Codes
Question:	1992 Eagle Talon (yeah yeah....mitsubishi) 2.0L non-turbo; manual tranny; 103,000 miles; Owned it since new. Couple of weeks ago the check engine light came on for the first time that I can remember. Engine seems to run a 'little' rough at times, but overall I cant tell much difference. It does have more trouble starting than usual (Good cranking and battery power though). The diagnostic codes retrieved are as follows: 13,14,21,25 -Which seem to be multiple sensor problems. Intake air temp sensor, thermostat sensor, throttle position sensor, barometric pressure sensor. Any suggestions on the order of solving the problem, or what to try first? Please help! Happy holidays!
Answer:	Jason, The IAT and BP sensors are right in your MAS. Check your air filter and make sure all the connections are tight. The TPS may have come loose or gone bad. Remove your throttle body, clean it out, and check all connections. If your throttle plate does not move freely, you may have bad o-rings on you throttle position sensor. Those should be replaced. The thermostat sensor is definately a strange one. Most time the check engine light comes on due to vacuum or other related air intake problem. The radiator components have their own dummy light on your dash. Try resetting computer (disconnect the negative battery cable for about 15 minutes than reattach). If you run your car for a few minutes and all the same codes come back, you may want to have your computer checked. The 1G DSMs (90-94 Eclipse, Talon, and Laser) had faulty computer components. The capacitors on the board would leak and ruin the board over time. People would get all sorts of strange code readings and engine problems. Typically, this only occured on the turbo models, but some bad capacitors may have found their way to the non-turbos as well. Good luck!
