Engine Check light

[Deano96GS]

My engine check light came on while driving, is there a way to check what is wrong? i know i had a neon before, and you would turn the ignition on-off-on-off for 5 seconds and the light would flash a certain amount of times, giving you a code, telling you the problem. How do i do that with These mazdas<P>mx3-boi@shaw.ca

ON V6's ONLY, the procedure is as follows:<P>Locate and open the "Diagnostic" box under the hood. It's behind the battery, on the firewall. Below is shown a representation of the pins inside the Diagnostic box:<BR> <BR>The pins labelled "TEN" (which stands for "Test ENgine" by the way) and GND (ground) are the pins of interest. Make sure the ignition is OFF and use a paperclip to jumper the TEN and GND pins together.<P>Turn on the ignition (do not start the car) and watch the CEL. After about 4-seconds, it will begin to flash any codes that may be stored. If there are no codes stored, the CEL will not flash (it will go out.)<P>Malfunction codes are generally 2-digit affairs although Mazda decided to get tricky. They include 2-digit codes that involve '0' (zero) as a digit. Code 02 is one example. Code 10 is another.<P>The codes are broken into a 10s digit and a 1s digit. The 10s digit is flashed first, followed by the 1s digit. The digits are distinguished by the length of time they flash the CEL. 10s digits flash the CEL on for 1.2-sec while 1s digits flash the CEL for 0.4-sec. Digits that are '0' (zero) flash the CEL exactly zero times.<P><BR>Here are the codes in order, followed by their respective descriptions.<BR><UL TYPE=SQUARE><LI>02 'NE2' crankshaft position sensor <BR><LI>03 'G' camshaft position sensor <BR><LI>04 'NE1' camshaft/crankshaft position sensor <BR><LI>05 Knock sensor<BR><LI>08 Volume Air Flow sensor (VAF)<BR><LI>09 Coolant temperature sensor (CTS)<BR><LI>10 Intake air temperature sensor (IAT)<BR><LI>12 Throttle position sensor (TPS)<BR><LI>14 Barometric pressure sensor <BR><LI>15 LHO2S inactivation error<BR><LI>16 Exhaust gas recirculation (EGR) system<BR><LI>17 LHO2S inversion error<BR><LI>23 RHO2S inactivation error<BR><LI>24 RHO2S inversion error<BR><LI>25 Fuel pressure regulator control solenoid<BR><LI>26 Canister purge solenoid<BR><LI>28 EGR vacuum solenoid<BR><LI>29 EGR vent solenoid<BR><LI>34 Idle air control (IAC) solenoid<BR><LI>41 VRIS #1 solenoid<BR><LI>46 VRIS #2 solenoid<BR><LI>67 LFAN relay<BR><LI>69 ECTF sensor <BR></UL><P>Any questions?
