2022年2月23日 · Truck dies after about 2-5 minutes lacks power. Changed the Ipr valve but still get code p2623. Just installed a rebuilt motor, long crank until low pressure oil idiot gauge turns on, then engine starts. ICP and desire icp seems to be perfectly correclated. Checked the plug and wire for the IPR valve, no indication of frayed wires.

2024年4月12日 · Code P2623 was up. 1st time. Went directly for the injection pressure regulator valve, turbo out, replaced, visually checked all the wiring, all still wrapped and not frayed ( a few connectors have been replaced over the last 3 years - they look good). So, tried starting a few times this AM, still no start.

2014年10月13日 · Often P2623 is related to the throttle body sync; try pulling the connector off the T/body and pressure reg sensor. This will throw two more codes. Go for a clear in Vin specific and OBD2 generic programs. Once cleared and re-switch on KOEO and see if p2623 is cleared but the other two remain. This will indicate a throttle body fault or sync issue.

2019年6月1日 · P2623 is an IPR circuit code and a fault there will cause a no start concern. Since you were just working on cylinder #8 which is right near the IPR my bet is on the wiring - most likely the connector is not fully seated and latched on.
