P06DD Oil pump pressure control not responding, as if stuck off

Engine oil pressure control circuit stuck off

P06DD in short

P06DD means the engine computer’s control of the variable-pressure oil pump is not changing oil pressure as commanded, as if the control were stuck off. Low oil level, a damaged pump control solenoid, debris in the pump or wiring faults are common causes. Check the oil now; stop if the oil warning comes on.

Many newer engines use an oil pump whose pressure the engine computer can change through a control solenoid. The computer compares what it commanded with what the oil pressure sensor reports, and sets P06DD when pressure does not respond as if the control is stuck off. GM uses P06DE for the opposite, stuck on.

Bulletins point at both simple and serious causes: low oil, or an oil change that left the filter and oil galleries empty; a broken pump control solenoid; debris jamming the pump; timing chain guide wear damaging the pump on some GM V8s; a failed relief valve on Chrysler’s Pentastar V6; and engine wiring harness faults.

Although the code sits among engine computer codes, the fault is usually in the oil system or its wiring, not the computer itself.

Most likely causes

  1. Low oil level, or an empty filter and gallery right after an oil change

    Common general cause
    Why it ranks here
    GM tells technicians to first check the engine oil level for P06DD, and GM PIP5844 covers P06DD from low or no oil pressure right after an oil and filter change.
    What would change this
    Rises if the dipstick reads low or the code appeared right after an oil change. Falls if the level is correct and the code returns after a few drives.

  2. Damaged or broken oil pump control solenoid (GM V8 trucks and SUVs)

    Supported by vehicle data
    Why it ranks here
    GM PIP5555 says the oil pump control solenoid may be damaged or broken when P06DD sets on 2015–2018 Silverado, Sierra, Tahoe, Yukon, Suburban and Escalade, with original or replacement pumps.
    What would change this
    Rises if commanding the pump control on a scan tool does not change oil pressure. Falls if pressure follows the command.
    How to test the engine oil pump

  3. Debris jamming the oil pump (GM 1.2L and 1.3L three-cylinder)

    Supported by vehicle data
    Why it ranks here
    GM service update A202302140 and its TechLink articles describe the oil pump sticking from foreign material on the Encore GX, Trailblazer and Trax, with an oil pump screening test.
    What would change this
    Rises on those models if the GM screening test fails. Falls if it passes.
    How to test the engine oil pump

  4. Engine wiring harness fault in the pump control circuit

    Supported by vehicle data
    Why it ranks here
    GM PIP5750A (2019–2021 Silverado and Sierra 1500) and PIP5932D (2024 Trax and others) point to engine wiring harness concerns behind P06DD.
    What would change this
    Rises if the harness shows chafing, a loose connector or an open circuit to the pump solenoid. Falls if the circuit tests good.

  5. Worn or damaged oil pump, relief valve or timing cover pump

    Supported by vehicle data
    Why it ranks here
    GM PIP5407 replaces the timing chain tensioner guide and a worn pump on some 2014–2016 V8s with low oil pressure; FCA has Pentastar V6 pumps checked for a failed relief valve; Jeep replaces the timing chain cover that holds the pump on 2022–2024 Renegade, Compass and Commander.
    What would change this
    Rises if a mechanical gauge shows low oil pressure with the correct oil level, or there is front-of-engine noise. Falls if real oil pressure is normal.
    How to test the engine oil pump

What to test first

Start at step 1. Each result tells you what it means and where to go next.

  1. With the engine off on level ground, check the oil level on the dipstick and note when the oil was last changed.

    Low risk

  2. Ask a dealer whether your VIN has a bulletin or service update for P06DD. GM, Chrysler and Jeep have issued several.

    Low risk

  3. Have a shop measure actual oil pressure with a mechanical gauge, compare it with the scan tool reading, command the pump control, and check the pump control wiring.

    Best left to a shopTool: mechanical oil pressure gauge, bidirectional scan tool, multimeter

    Warning:The engine runs with hot oil under pressure and the sender is removed for the gauge. Leave this to a shop.

Symptoms

  • Check engine light with no change in how the engine runs
  • Engine will not rev above about 3,300 rpm (Jeep Renegade, Compass, Commander)
  • Oil pressure low warning or message Gets more serious: stop and have it checked.
  • Ticking, rattling or knocking from the engine Gets more serious: stop and have it checked.

How to fix

  1. Check the oil level with the engine off on level ground and top up to the full mark with the oil your owner’s manual specifies.

  2. Ask a dealer whether your VIN has a bulletin or service update for P06DD.

Parts and cost context

  • Engine oil pump:On many GM and Chrysler engines the pump sits behind the timing cover or in the oil pan, so replacing it is a major job; Jeep’s fix replaces the timing chain cover that houses the pump. Labour varies; get a quote.

P06DD questions

Is it safe to drive with P06DD?

Check the oil first. If the level is right and there is no oil warning or noise, drive gently to a shop soon. Stop the engine if the oil pressure warning comes on.

P06DD showed up right after an oil change. Why?

GM has seen P06DD when the new filter and oil galleries were empty at start-up. Confirm the oil level, clear the code and see whether it returns.
