P1053

A P1053 code just popped up on my '98 Explorer (V8, 94,000 miles). I know
that it means 'B2S1' oxygen sensor sluggish to respond. The manual lists
about 20 different reasons, before it gets to the obvious suggestion to
replace the sensor. The vehicle has been well maintained and I have no
reason to suspect coolant seepage into the cylinders or poisoning the
sensors with silicone products. For a good measure I will clean the MAF
(listed as one possible cause), though I can't see how it would affect only
one side of the engine. Frankly, the other listed possibilities appear far
fetched.
So here is my question to those who do this for a living and/or have access
to TSB's: is this failure common at all? If so, are you aware of any
'typical' reason other than aging of the sensors?

Should be P1053 - sorry!

Sorry for the typo. The DTC is P0153.

It's P0153...

Well, no harm done, because nobody responded yet . But hopefully I got that
DTC right now. P0153, P0153, P0153... Any takers?

Re: It's P0153...

The first step of the PPT directs you to perform a KOER test..... You could
simply replace the sensor, but this is no guarranty of a fix.

Best advice... either cut to the chase and replace the sensor or follow the
PPT EXACTLY.

If you were in my shoes.... you would catch flack for doing the PPT and then
replacing the sensor and you would catch flack for replacing the sensor
without performing the PPT (if the sensor didn't fix it). You cannot pick
and choose which step you will perform next since the results of one test
influence the next test.

Re: It's P0153...

Thanks, Jim.

KOER is not finding anything and the fuel trims are almost perfectly
centered. But looking closer I found a 'pending' code for intermittent IAT
output voltage. Seems to be poor contact to the PCM, because I can wiggle
the connector and the IAT reading jumps. Probably nothing to do with the
sluggish H2OS code, but perhaps there is one more pin with a poor contact
there.

The fun continues...

Re: It's P0153...

I am the last one to throw parts at a problem, but compared to past
struggles with oxygen sensors on other vehicles, the B2/S1on the Explorer
was so easily accessible that I could not resist the temptation. By now the
monitors have completed without a hitch and P0153 has not returned.
If only figuring out that intermittent contact on the IAT connection had
been so easy...

Re: P1053

Hi there i have a 2000 ford explorer xls and was having the trouble codes
come up for the oxygen sensor. I would clear the codes, 173 and 174 and
upon driving it less than 2 miles the truck would hesitate and then the
engine light came on again and i did a good inspection under the hood and
was puzzled by the issue. I pulled all of the spark plugs out and bought
new ones and set the proper gap and that fixed my problem. The book says
that the engine was running to lean and to replace the sensor. I think the
gap was less than .54 and it cause it not to get hot enough to burn the
correct amount of air/gas artio so there thus causing my issue.

Re: P1053



x-no-archive: yes

Don't read too much into what the manual is telling you.... there are
virtually no codes that tell us to change parts. They do lead us to test
routines that *may* have us change parts. In the case of lean or rich
mixture codes, we must first determine if the mixture is indeed lean or
rich.

In your case, it sounds like faulty spark plugs were creating ignition
driven misfires. Each misfire would send large amounts of unused oxygen down
the pipe.... since the O2 sensor can only measure oxygen (and nothing else),
the PCM would see this as a "lean" indication and result in a lean mixture
code. One of the first steps in diagnosing DTCs is to determine if codes
retrieved are causal or symptomatic.

HTH.
