I heard that if i'm getting a check engine light , the ecu goes into limp mode and vtec won't engage is this true?

 

yes. but not all check engine lights will put the ECU in limp mode.

 

will a code 10 oxygen sensor put it in limp mode?

 

no.

code 10 is not the O2 senro tho

code 1 is, code 10 is the intake air temprature sensor

 

ok well i get the 1 long blink when checking for codes is that the intake air temprature sensor? if so will it cause limp mode?

 

what codes do put ecu in limp mode. IM throwing like 3 and I my vtec hits, let me tell you it hits. The new M3 driver i found on the freeway will tell you it hit on him too! BUMP FOR VTEC.
Im throwing the dist. code, knock sensor and O2 sensor.

 

True limp mode is a very unpleasant thing: 3000rpm rev limit, unbelievable studdering, no power at all. Safe mode or whatever you want to call it is different, just giving more fuel and a little less timing. If your ecu was in limp mode, you would know, trust me. There's not much short of an internal failure that will cause it though. As far as the safe mode not letting vtec work, I'm not sure how much has to go wrong. Obviously a lot if 3 codes allow it to engage.

 

Where should i start to check to find out why v-tec isn't working?
