Guess I should mention that this seems to have started the following day after allowing the dealer to do a steering assist recall computer update. Perhaps this is just coincidental but thought I should mention it. The test light should be illuminated and bright. Turn the ignition off, disconnect the Oil Pump Solenoid harness connector. Any chance you could post a picture? P06da engine oil pressure control - circuit open circuit. Default actions, MIL light illuminate. P06DA Code - Engine Oil Pressure Control Circuit / Open.
Possible causes P06DA code: - Oil pump solenoid control circuit shorted to voltage. Diagnostic test P06DA code. If no problem are found, replace the Oil Pump Solenoid. Is there any voltage present? The circuit is monitored for a short to voltage when the oil pump solenoid is commanded off. With the scan tool, read DTC and record on the repair order. Powertrain Control Module (PCM). The test light should be off except for a brief period immediately after turning the ignition on. P06da engine oil pressure control - circuit open source. Is the test light illuminated and bright during the actuation and was it off when required? Thank you for the quick reply!
I started the engine and the check engine light went off, drove it down the road pretty aggressive and all seems to be good now. Measure the resistance between ground and the Oil Pump solenoid ground circuit at the Oil Pump solenoid harness connector. P06da engine oil pressure control - circuit open access. Probimg the PCM harness connector will damage the PCM terminal resulting in poor terminal to pin connection. I drove the truck down the road a ways and the check engine light came back on. Not sure how it happened but the wiring harness shrank and broke the plug end off and they had to put in a new harness and the low pressure stage of the pump worked after that. Hold engine speed greater than 1000 rpm for at least one minute. 0 volt, t he Powertrain Control Module (PCM) monitors the oil pump solenoid control circuit for an open or short to ground when the oil pump solenoid is commanded on.
Start the engine and allow it to reach normal operating temperature. 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. Check the Oil Pump solenoid ground circuit. Next area I decided to look at was the engine module. April 21, 2017 Add Comment.
The main wire harness clip that locks the harness was broken. With the scan tool, actuate the Oil Pump Solenoid control to the ON (100%) position. So I spent $90 for nothing. Where is that wire harness located? The solenoid broke which is not uncommon in these trucks.
I have been getting the same code on my 2014 5. YES, repair the Oil Pump Solenoid control circuit for a short to ground. Can anyone tell me if that is true or not? I unplugged the harness and plugged it back in and wiggled it down tight and locked the arm back down on the plug. 3- Oil Pressure seems higher now, 40 to 50 psi below 1000 RPM and 60 normal driving - 75 passing. Well stumbled on the fix to my problem. NO, perform the PCM intermittent condition. Is there continuity between ground and the Oil Pump Solenoid control circuit? Is the resistance below 3. I will replace the oil pressure sending unit today in hopes that it fixes the issue. 2- Oil Gauge works - goes to zero and pegs and drops to 40 to 50 psi on startup. 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. After changing the oil pressure sending unit and disconnecting the battery, the check engine light went off.
Is the DTC active or pending P06DA code? Turn the ignition off, disconnect the PCM C2 harness connector, check for continuity between ground and the Oil Pump Solenoid control circuit at the oil pump solenoid harness connector. Check related PCM and component connections. Caution: Do not probe the PCM harness connector. 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. 3 crew cab Silverado and I've taken it to 2 places and they have told me I have a faulty solenoid valve which is located in the oil pump. The DTC will not be set unless cam phasing becomes active, which may not occur if speed never leaves idle.
Turn the ignition on, with the scan tool, record the related Freeze Frame Data and clear the DTC in the Powertrain Control Module (PCM). NO, repair the Oil Pump Solenoid ground control circuit for an open high resistance. Compare the brightness to that of a direct connection to the battery. I paid $2200 to replace it because all the belts have to come off, timing chain cover, and oil pan. Check for an active DTC. I will have to take it in to be diagnosed, unfortunately I am not under warranty anymore.. My truck had a permanent p06DD code with the check engine light going on and off for about a year. P06DA code - With the engine running, w ith the battery voltage above 10. Trying to understand the relationship to control circuit, oil pressure sending unit, computer module and 2 phase oil pump and if I have a more technical issue than a oil pressure ending unit.
