Darn engine light!!!

[daniel_r93]

Ok let me start by saying iam new to cb7 but i love site so far here's my problem engine light comes on but when checking ecu with the old wire trick engine light doesn't blink at all now i read about this else where and the one stuck out was the 0 code dead or failing ecu but a third opinion on it is needed thanks...

ECU pushed the daises. Swap another ECU in and see.

make shure you are bypassing the blue connector......

[daniel_r93]

well how exactly? to bypass

[daniel_r93]

Well also i just checked the ecu to see if it was even flashing and nonthing dang well plan on swapping another ecu in this friday

[daniel_r93]

alright

went to get a another ecu and still that one the cel didn't blink once like the old one damn what to do next

[daniel_r93]

ok i bypassed it just now!!!

got a ecu code 43 after i came from a buddy's house left her running with check engine light and jumper the ecu wire's and she finally flashed a code problem solved for now i guess

Code 43 is most likely your oxygen sensor. Replace it with Denso or NTK. No Bosch... they don't work properly.

thanks

that's what i put in there was a bosch o2 sensor think i'll swap-out fuel filter
only 3.99 but damn just brought that o2 sensor

thanks

Yeah, it's a shame... if someone replaces their o2 sensor without searching on here first... often just going to Autozone or a similar store and asking for a 90-93 Accord o2 sensor, they end up with a Bosch... and wasted money. I've only known a handful of people to have luck with the Bosch. Apparently you can modify them to work, but I can no longer find the information showing how to do that. Rockauto.com has Densor sensors for $40 now, so there's no point in ever getting a Bosch anyway (the proper sensors used to be over $100... $80 was a steal...)
