P2293 Code: Fuel Pressure Regulator 2 Performance

The second fuel pressure control stage can't hold its target; on VW/Audi 2.0T often the high-pressure pump.

Some engines control fuel pressure at two points, and the number 2 tells you which one is involved. On most direct-injection gasoline engines that use this code, such as the VW and Audi 2.0 TFSI, regulator 2 is the metering valve on the camshaft-driven high-pressure pump, while regulator 1 is the demand-controlled low-pressure supply; a few makers assign the numbers differently, which is why this page is marked as varying by model. P2293 sets when the regulator is being commanded but rail pressure doesn't follow the target within the allowed tolerance, typically under heavy load when the pump has to work hardest. On the older 2.0 TFSI the classic root cause is a worn cam follower between the camshaft lobe and the pump plunger, which shortens the pump stroke; a sticking regulator valve or a weak low-pressure supply can produce the same result.

Can I keep driving? Short, gentle trips are usually possible, often in reduced-power mode, but the engine may stumble or stall under load. On VW/Audi 2.0 TFSI engines, have the cam follower checked soon: once it wears through, the camshaft lobe is damaged and the repair cost multiplies.

Symptoms

  • Loss of power or limp mode under hard acceleration

  • Engine stalls or is hard to start when hot
  • Check engine light with P0087 or misfire codes alongside
  • Ticking from the high-pressure pump area that grows louder

Possible causes

Ranked by how often each cause is behind this code (editorial estimate).

  1. Worn cam follower between camshaft and high-pressure pump (typical on VW/Audi 2.0 TFSI) 30%
  2. High-pressure pump worn internally or its metering valve sticking 24%
  3. Weak low-pressure supply: tired in-tank pump, pump control module or clogged filter 16%
  4. Connector or wiring problem at the regulator valve causing erratic control 10%
  5. Rail pressure sensor reading inaccurately, misleading the control loop 10%
  6. Poor fuel quality or contamination affecting the pump 6%
  7. Engine software needing an update 4%

Diagnosis step by step

Diagnostic flow: P22931Log commanded versus actual railpressure2Confirm the low-pressure side3Inspect the cam follower4Check the regulator valve andconnector5Verify the rail pressure sensor6Retest under the original conditions

  1. Log commanded versus actual rail pressure

    Record desired and actual high-pressure values during a full-throttle pull in second or third gear. Many GDI engines run roughly 40 to 50 bar (580 to 725 psi) at idle and well over 100 bar (1,450 psi) under load; check your engine's specification. Actual pressure falling away only at high load points to the pump or follower, not the sensor.

    Tools: OBD-II scanner

  2. Confirm the low-pressure side

    Check low-side fuel pressure with a gauge or the low-pressure sensor value, typically around 4 to 6 bar (60 to 90 psi) on demand-controlled systems. If it sags under load, fix the supply first; a starving high-pressure pump can't reach its target.

    Tools: Fuel pressure gauge, OBD-II scanner

  3. Inspect the cam follower

    On engines with a cup-type follower under the pump, relieve fuel pressure, remove the pump and pull out the follower. A worn-through spot or a dished center on the contact face means it must be replaced, and the camshaft lobe should be checked for scoring before the new part goes in.

    Tools: Torque wrench, Flashlight

  4. Check the regulator valve and connector

    Inspect the valve connector on the pump for corrosion or fuel seepage and measure the coil resistance against spec. A valve with the right resistance can still stick mechanically, so watch the regulator duty cycle: a command pinned near its maximum while pressure lags confirms the pump can't deliver.

    Tools: Multimeter, OBD-II scanner

  5. Verify the rail pressure sensor

    With the engine off and cooled, the rail sensor should settle near the low-side pressure, and it should agree closely with the target at a steady idle. A sensor that reads high or drifts can make the regulator appear at fault.

    Tools: OBD-II scanner

  6. Retest under the original conditions

    After repairs, repeat the logged full-load pull and compare actual with desired pressure. Clear the code only after the values track within a few percent.

Notes by brand

Volkswagen

On the 2.0 TFSI in the Mk5 GTI, Jetta GLI and Passat, the high-pressure pump rides on the intake camshaft through a small cup-shaped cam follower. It is known to wear through, especially on tuned engines, leading to low rail pressure and P2293 or P0087; many owners inspect it at regular intervals.

P2293 on Volkswagen in detail

Audi

The same 2.0 TFSI follower issue affects the A3 and A4 of that generation. If the follower has worn through, the intake camshaft lobe is often damaged too, so inspect it before fitting a new pump or follower.

Emissions / smog test impact

Will fail

P2293 turns on the check engine light, which fails an OBD-II emissions test. After repairing it, drive until all monitors, including the misfire and fuel system monitors, report ready.

Frequently asked questions

What does 'regulator 2' mean?

The engine has two stages of fuel pressure control, and the manufacturer numbers them. On most engines using P2293 it's the high-pressure pump's metering valve, but it can differ, so confirm with service information for your model.

How can a cam follower cause a fuel code?

The follower transfers the camshaft lobe's lift to the pump plunger. As it wears, the plunger's stroke shrinks, so the pump pushes less fuel per revolution and pressure falls under load.

Is a new high-pressure pump always needed?

No. Check the low-pressure supply and the cam follower first; either one can cause this code on a perfectly healthy pump. Replace the pump only when the pressure data and inspection point to it.

Can I keep driving with P2293?

Gently and briefly, yes, but the car may lose power suddenly. If a worn follower is the cause, every mile adds wear to the camshaft lobe, which is far more expensive to replace.
