Drive Cycle with Check Engine Light on?

10

Asked by Jul 21, 2016 at 08:44 AM about the 2000 Ford Escort ZX2

Question type: General

Can my car run a drive cycle with the check engine light on?  

I have a 2000 Ford Escort zx2 that I've recently disconnected and
reconnected the battery, clearing the history so to speak for the emissions.  
I need to run through a drive cycle to be able to get my car emissions
tested but the check engine light is on.  After driving 150 miles, the car still
hasn't gone through the drive cycle, will it not go through if the check
engine light is on?????

Scan the car for the 4 digit codes and post back here. Most local auto parts shops will do it for free.

p0117 - low voltage regarding the ect sensor, supposed to be because the engine is hot; however, I am 95% sure the ect sensor is bad and am in the process of replacing it (waiting for part). p1000 - drive cycle not complete

You need to fix the problem that's triggering the check engine light. Clear the computer with a scan tool. Disconnecting the battery will not clear the computer on an OBD II vehicle (1996 thru current). Then drive normally for a few days with the gas tank between 1/4 and 3/4. No more and no less in the tank. The computer will run the diagnostics and set the readiness monitors. You can pass an emissions test, under Federal Regulations, with 1, but only 1, readiness monitor not set. HTH. -Jim

Thanks Jim, I replaced the ECT sensor again (I had already done it a few weeks ago) after hooking it up to a scan tool and seeing it was registering the coolant temp at 300+F when it was nowhere near that temp. Once I put the new sensor in, I cleared the codes and haven't had the light come on yet. Thanks again
