PO153 code message


I have a 1997 Explorer that displays the engine code P0153 when hooked up to an analyzer. Also my fuel cap light is on and a loud valve chatter has begun to develop. I know that some of this could be as result of a bad EGR valve, what do you think?

Re: PO153 code message

Not sure where the EGR valve fits into this.... P0153 shows HO2S11 has
failed a response test... possible causes include air and/or vacuum leaks,
fuelling concerns... One would need to check the performance of HO2S21 to
see if the concern is indeed common to both banks.... An EGR concern would
affect both banks on one of these motors... I don't believe they are running
ported EGR...

I the fuel cap light is on.... well, I guess I would check the fuel cap....
if that tests OK, I'd think about a gross EVAP leak - which could also
trigger the P0153.

Sorry, no thoughts on the valve chatter.... oil condition and level.... base
oil pressure.... these are only a couple of considerations..

Jim,
I am also experiencing the same P0153 code on my 96' 4.0 ohv model. (only
50k miles)
I replaced O2 sensor on the indicated bank twice but code comes back within
100 miles.
I feel no discernable loss of engine performance or mileage though.
What other likely causes should I be closely monitoring?

Re: PO153 code message

Without knowing if the other bank is getting close to setting the same code,
I'd have to suggest checking things that are "bank specific"... many times,
these can be a vacuum leak of some sort or another.

At present, I'm waiting for the warranty nazis to OK my desired repair on a
2004 5.4 3V. An exhaust valve spring broke and the customer continued to
drive the unit... The upstream cat plugged off and reading fuel trims showed
a wierd pattern. In all honesty, the "good" bank looked bad. Multiple codes
clouded the issue.

No P0153 was generated though I believe a restricted cat *may* affect O2
performance.

Even now, we're still learning about long term effects with some of these
systems....

When I had my 92, I found that te center plugs on both heads had fouled....
the cause was the lower intake gasket had failed.... If there is a spark
plug that misfires intermittently, I would think that this may offer up the
P0153.....

Sorry I can't be any more help without some specific testing...
