HOW-TO: Mechanical CEL Fix for a Header

This is a link to the Duratec "cheater" fix sticky. Same trick mentioned by ferret15.

Don't know if the Zetec electronic "cheater" from that thread has been made to work on a Duratec. Def. wasn't written for a heater code cheater.

Which O2 you're working on wasn't mentioned.

Do you have an O2 mounted further up the header? First O2 is the one that would give a "lean" code.

Is this a new install? or have you been running it a while.

Lots we can't guess from the initial post, tryin' to read between the lines from the symptoms mentioned.

First off. whatever you're trying to cobble together, is wrong.
Stop.


The 'cheater' it to fool the ECU into thinking the second O2 sensor is reading normal.
It has nothing to do with the heater circuit.

Stop trying to do the 'hack' on the first O2 sensor.



If the fuse is good, there's power to the fuse and continuity from the fuse to the connector, then the sensor is dead. Replace it with anything but Bosch.

Again, stop dicking with fooling the ECU and fix it correct.

Yeah the fuse has power, and none of the wires are frayed. Guess I'll have to break down and get a new sensor.

I've been running the header for almost a year. The sensor went bad two or three days after I got the tune to remove the cel related to the sensors from the old header. Drove it about a week with the header without a tune.

New Sensor & use the tune sounds like the best fix.

Just what CEL is the first question.

Why you did the "cheater" would be another.

What brand Sensor could help as well, seen poor life from some from reports in the Forum.

Luck

I hate to kick up an old thread like this but I just did this this weekend after having a P420 code on my SVT for a long time. Its been a week (including commuting every day and a 6 hour drive a few days ago) and my CEL has stayed off! Hopefully NYS doesnt notice my little bit of wiring when i got for a an inspection...

Thanks for the how to
