But I read in another forum that long term use can cause damage to the engine so who the hell knows! 2- Oil Gauge works - goes to zero and pegs and drops to 40 to 50 psi on startup. If no problem are found, replace the Oil Pump Solenoid. With the oil pump solenoid commanded off, the PCM detects voltage on the oil pump solenoid control circuit.
According to this video apparently if the solenoid breaks the oil pump is still good which would explain the oil pressure gauge still getting mostly normal pressures. Perhaps this is just coincidental but thought I should mention it. Is the DTC active or pending P06DA code? Where is that wire harness located? P06da engine oil pressure control - circuit open access. P06DA code - With the engine running, w ith the battery voltage above 10. Had to bring my truck in for the repair, which ended up being covered by my warranty. After changing the oil pressure sending unit and disconnecting the battery, the check engine light went off. I have been getting the same code on my 2014 5. The test light should be off except for a brief period immediately after turning the ignition on.
The circuit is monitored for a short to voltage when the oil pump solenoid is commanded off. Is there continuity between ground and the Oil Pump Solenoid control circuit? YES, verify that there is good pin to terminal contact in the Oil Pump Solenoid and Powertraint Control Module connectors. 3- Oil Pressure seems higher now, 40 to 50 psi below 1000 RPM and 60 normal driving - 75 passing. With the scan tool, read DTC and record on the repair order. Turn the ignition on, with the scan tool, record the related Freeze Frame Data and clear the DTC in the Powertrain Control Module (PCM). Compare the brightness to that of a direct connection to the battery. I will replace the oil pressure sending unit today in hopes that it fixes the issue. YES, repair the Oil Pump Solenoid control circuit for a short to ground. P06da engine oil pressure control - circuit open cylinder. Check for an active DTC. Hold engine speed greater than 1000 rpm for at least one minute. NO, repair the Oil Pump Solenoid ground control circuit for an open high resistance. The error code indicates it is a faulty solenoid, but there are other test they run in the diagnostic process.
Some of the stuff I read online that is not exactly related to my exact issue, but indicates a computer module and 2 phase low/high pressure oil pump? The DTC will not be set unless cam phasing becomes active, which may not occur if speed never leaves idle. 1- Engine Check Light on (not flashing). Thank you for the quick reply! Reconnect the PCM C2 harness connector, turn the ignition on, using a 12 volt test light connected to ground, probe the Oil Pump Selenoid control circuit at the Oil Pump Selenoid harness connector. I paid $2200 to replace it because all the belts have to come off, timing chain cover, and oil pan. P06da engine oil pressure control - circuit open office. Set conditions, w ith the oil pump solenoid commanded on, the PCM detects either now current draw indicating an open or excessive circuit temperature indicating a short to ground. Measure the resistance between ground and the Oil Pump solenoid ground circuit at the Oil Pump solenoid harness connector. Caution: Do not probe the PCM harness connector. Powertrain Control Module (PCM). They had to run test at Chevrolet dealership to diagnose. Check related PCM and component connections. Well stumbled on the fix to my problem. Check the Oil Pump solenoid ground circuit.
Apparently the mechanic at the dealership broke the clip and didn't plug it back in right when they did the steering assist recall update. The test light should be illuminated and bright. The main wire harness clip that locks the harness was broken. P06DA Code - Engine Oil Pressure Control Circuit / Open. NO, perform the PCM intermittent condition.
