Bad Speed Censor = CEL? - Honda Prelude Forum

Jape · 03-12-2002, 08:43 PM

About the same time my speedometer stopped working (you guys diagnosed it as a bad speed sensor), my check engline light also came on...

I noticed when I run the engine hard, the check engine light comes on...

Sometimes I'm just cruising and it comes on..... I still haven't fixed the speed sensor yet (someone sell me one) ... just wondering if the speed sensor could contribute to a Check Engine Light, or if I got bigger problems...

not yet, I'm too lazy.. I remember a website somewhere with detailed instructions... I bookmarked it but it got lost in a sea of other useless links I bookmarked.. anyone still got that link?

I took the radio out, I think i see those plugs, but nothing is plugged into them, maybe its a VTEC thing? Well i'll try and bridge it later.

they are plugged into dummy sockets, just push the tab on it and pull it out.

oh, u didnt need to take out ur radio, if u can squeeze under the dash, u will see them in the area behind the radio
