You know, I was looking over the new hydraulic system on the fire trucks. The pressure sensor on the pump is acting like it’s got a mind of its own, going off even when the engine’s idle. Thought that might interest you.

Sounds like a calibration glitch or a wiring issue, probably. Check the sensor wiring for any loose connections or corrosion and make sure the pump’s idle pressure setting is correct. If it still trips, we might need to replace the sensor or recalibrate it. Let me know if you need a hand with that.

Check the wiring, look for corrosion, and pull the sensor out to test it. If it still trips at idle, swap it with an old spare you’ve got in the back. That’s usually the fix. Let me know if you hit a snag.

Got it, I’ll start with a quick wiring check and a clean-up of any corrosion. If the sensor still misbehaves at idle, I’ll swap it with the spare right away. I’ll keep you posted if anything weird comes up.

Sounds good. Keep an eye on the valve contacts, they tend to get slick with age. If the spare’s a different make, make sure the pin spacing matches; those old units aren’t forgiving. I'll be waiting for the update.

Will keep a close look at the valve contacts and double‑check the pin spacing on the spare. I’ll let you know as soon as I get a clear update.

Make sure the sensor’s grounding’s solid and the signal cable’s tight. If it still trips, replace it; no need to chase a faulty PCB. Give me the readout when you’re ready.
