I have a GRT sensor which is occasionally providing a reading of 38 psi which puts me into the out of limits condition for the Chelton displays. Normal reading is about 29 psi. part total time is about 450 hours. anyone else had sensor problems? I carry a replacement in the tool/parts box so I can change it but trying to confirm that it needs to be replaced. Engine continues to perform properly.

Don't know if it's the same sensor, but my one from Dynon lasted about 25 hours, before it started "oscillating" with the boost pump off. Replaced it, and the problem was fixed... for about 5 hours. Seeing the same issue again.

My normal pressure is in the low 20’s, but I saw some spikes after the first year…….ended up being a faulty ground connection. The crimp just was not good enough. Worked fine ever since. 170 hours.

have not decided what to do at this point but may look for an automotive solution or a certified solution.

I found that the VDO sensors used for oil and fuel pressure are 360004 and 360003 and are automotive senders. I checked with EI and found that we are "locked in" to VDO sensors check for pressure. I did replaced egt probes with EI and have had no further problems with egt probes burning /disintegrating.

I just replaced my second GRT fuel sensor a few weeks ago. Both sensors started giving erroneous high readings intermittently in my Cheltons and on Vertical Power. Sandy at GRT says this is pretty common with this sensor. It is a five minute job to swap sensors, but it is a PITA when it starts giving you false alarms. I changed the first one at approximately 175 hours, and this recent one at about 350. I can't remember the cost, but I think it was in the $35 to $45 range.
