hi guys,
long time since my last visit..
just want to share some code 14 IACV issues on JDM small ecu
some issue can be solved by replacing the two resistor R62 and R63 and Q8, but try the resistors first.
however, i have one ECU that i have replaced R62 and R63 and Q8, no cel upon key on. idle goes up and down upon start. code 14 after 4-5 sec when engine is running
the iacv pin on the ecu does not hold up any voltage, usually a good known ecu will have 9V when engine is on
any ideas is appreciated..
other question is.. a steady CEL means with no code thrown is board problem. however, if steady CEL with no code thrown but if you pull a sensor plug, it will throw the specific code. but when you re install the sensor plug and reset the ecu. steady cel again no code thrown.
so the ecu reads sensor problems but when all sensors are working. there is steady cel with out a code thrown
