Guess that would be pulled out of a junk car and washed off. :haha:

I thought the Powertrain Control Unit (PCU), Powertrain Control Module (PCM) Electronic Control Unit (ECU) and Electronic Control Module (ECM) are different names for the same critter.

whatever you call it, apparently it's very uncommon/rare for it to go bad.

it figures.

OK, reading through the factory manual instructions for troubleshooting the P1519 code, Honda calls the computer the "ECM/PCM".
That means it would be covered under warranty if it were under 8 years/80k miles. Since you're well under on the mileage, it wouldn't hurt to cry on Honda's shoulder, starting with the dealer, and working your way up Honda's chain.

awwww; you looked up the codes for me. Sweet!

My check engine light is now off. After the application of $800+

it better stay off!

The Cellar Car had the nerve, again, to simply stop acting wrong. The Check Engine light is still lit, but the engine is now running normally.

I believe the Cellar Car is self-healing.

mutant transportation!

That is how most all failures normally happen.

For example, a car with about 100,000 miles sometimes would knock during acceleration from idle. Dealer swore they could not repeat the problem. Eventually I isolated the problem to but a few parts, but could not see anything wrong. Well I took out the distributor (the #1 suspect) and disassembled it. Found grease that lubricated the centrifugal and vacuum advance was sticky. Have since learned this going 'sticky' can be a problem with lithium greases in ten years. Sometimes ignition timing would get stuck until heat or extended operation freed the part.

Finding failures means first using logic to minimize a problem to certain suspects. That is what the check engine light does.

For example, what could cause intermittent failure - without that check engine code and other important facts? ERG valve gets intermittently stuck. Fuel pump is slowly failing - pressure too low - so that sometimes the injectors cannot compensate for that low pressure. Filter partially clogged. Intermittent leak in critical vacuum line. Temperature measurement device is intermittent - not always reporting correct temperature. Device that measures air flow is intermittent. Sticky or worn injector. Oxygen sensor reporting incorrect values. Cracked distributor. Electronic load sensor fails. Any connector is corroded causing varying sensor inputs to the computer. Bad spark plug wire. Partial obstruction in the exhaust manifold. Atmospheric pressure sensor failure.

And this is maybe 2% of possible suspects. A list that becomes massively smaller with that diagnostic code or other symptoms. In every case, the part is constantly defective causing intermittent failures. The problem has not gone away. It is simply a classic intermittent.

Based on how it was acting, this is my guess.

With the Cellar car, I thought who ever bought that part is responsible for its upkeep. Let me know if the ashtray is responsible for the problem.

classicman 04-15-2010 10:09 PM

I'm so anal - I went and found the damn thread and looked it up -
Brian got the ashtray
You had the glovebox

HungLikeJesus 04-15-2010 10:12 PM

Thanks, classic, that's good to know - 85% of these problems are directly attributable to the ashtray.

classicman 04-15-2010 10:24 PM

Bwaaaaaaaaahahahahah
