My 2006 Chev Impala 3.5l v-6 just showed trouble code P0690. I cleared the code by disconnecting the neg battery lead. It was ok for first start but showed again on the second start. What is it?


POSSIBLE CAUSES FOR THAT CODE OF A CHEVY ARE:
WEAK BATTERY
FAULTY COMPUTER OR ECM (Engine Control Module)
BLOWN ECM FUSE
ECM WIRE HARNESS IS OPEN OR SHORTED
ECM CIRCUIT HAS POOR ELECTRICAL CONNECTION.

How to replace ecm


Check the fuse for the ecm before replacing it. If you have a ford eec diagnostic try to get the codes. If you don't have a eec code reader there is a way to get the codes out by counting dashboard blinks. If you can get the ecm to output the codes the ecm is not bad.

I recently replaced injectors on a hilux 2KD FTV engine,2007.I understand i need to enter the code appearing on the new units to the ECM.I,ve tried to do so but the error code P1601 EEPROM still appears on...


hilux 2KD FTV , P1601 MEANS:

Type Powertrain - Manufacturer Controlled DTC - Manufacturer Controlled Description ECM Overtemperature
Cause Engine running, then the PCM detected an internal temperature of over 221F or an internal temperature of -58F or over 284F.
SO, it is a PCM error, tep is too high normally, or you can ask the 24 hrs live technical support vas5054a, they will like to help you, good luck

Lost pwr for takeoff, and gauges all going haywire and overcharging battery


Did the overcharge or voltage regulator problem go away with the new ECM in it? If so the transmission code.. (turbine speed sensor input) code is probably another problem that the Jeep has.. and the ECM will not fix that, but the input speed sensor that it may need is not very expensive.

ecm goes bad it will go in limp mode, vechicle will run poorly check engine light will stay on vechicle wont start.you need to use a code scanner check for ecm fault code, if check engine light not turning on when you start vechicle could have blowed ecm fuse or wiring problem, could have loose connection at ecm electrical connector or ecm getting poor ground but first check for a defective ecm using a code scanner.
