1turbofocus If you were not so hard headed about things you would turn off the POS EGR

iminhell We used to have a decent one at O'reilly but cooperate took it back.


I did find this though, randomly:

I/M Readiness Indication
o o
If the inferred ambient temperature is less than 32 F, or greater than 140 F, or the altitude is greater than 8,000
feet (BARO < 22.5 "Hg), the EGR monitor cannot be run reliably. In these conditions, a timer starts to accumulate
the time in these conditions. If the vehicle leaves these extreme conditions, the timer starts decrementing, and, if
conditions permit, will attempt to complete the EGR flow monitor. If the timer reaches 500 seconds, the EGR
monitor is disabled for the remainder of the current driving cycle and the EGR Monitor I/M Readiness bit will be set
to a “ready” condition after one such driving cycle.

I realize it's talking ambient temp (AIT) but being the only codes I ever get are EGR ones it's all that makes sense for my wonky idle. Have to get that fixed at some point.

1turbofocus I would find some one with a scan tool and doublt check , If in fact you have a 180 in there and your 140/150 then its bad and open

I have found the dash to bo off before and never used it again

iminhell 180* I think.
Dash test mode (I mean that is what the ECU is seeing, isn't it?)

I don't have an IR gun or any other way to verify temp. But it seems correct. Around 180-190 the reservoir starts transferring coolant. So I think it's close to accurate, sensor is brand new so It should be.

1turbofocus What thurmostat is in it now ? How are you checking temps now ?
