Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

6 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

So we've gotten a LOT of rain lately, and I'm noticing my CEL comes on after the rains during quick acceleration. I'm getting P0450 & P0197 (see pic): It seems suspect that I get these after a rain and hard acceleration - so could there be a short somewhere being triggered by water runoff? Thoughts?

POST 2Original post

Those sensor connectors should be weatherproof. The DME plugs are not though. Do you have a cab? Also, those two are going through different wire looms. Have you tried to reset the DME and see if the codes come back? The repair manual calls for sensor replacement for P0450. For P0197, you can test the sensor resistance from the DME side once that DME plug is removed. It will be very difficult to get to the sensor and its connector as it's in the middle of the engine.

POST 3 / ORIGINAL POSTEROriginal post

Yeah, it's a Cab. Thanks for the leads. Will keep everyone posted.

POST 4 / ORIGINAL POSTEROriginal post

Btw, I have cleared the codes via durametric and they came back, but it's been raining until yesterday I'll clear again and see if they come back.

POST 5Original post

Wet under the seats? Water sloshing around under the battery? Make sure the drains under the battery are clean.

POST 6 / ORIGINAL POSTEROriginal post

So I checked the battery drains - all clear. No moisture inside that I could detect. Cleared the codes again and so far, haven't come back. And it only rained once since then, but so far so good. Thanks all for the leads. I'll report back if they show up again.
