P052E on Honda by model: symptoms, diagnosis and fix
L15A (2007-2013) and L15B (2015-2020) engines are prone to excessive oil consumption. Normal consumption approximately 1 quart per 1,000 miles, but some units burn significantly more. PCV valve clogging and worn valve guide seals are common causes. Some owners report consumption stabilizes after 50,000 miles.
Common Symptoms
- Oil level dropping between oil changes
- Burning oil smell from engine bay
- Blue smoke from exhaust (may be slight)
- Oil level warning light illuminated
- Low oil pressure at idle
How to Fix
Check the oil level every 500-1,000 miles. Use the oil grade Honda specifies for your model year (5W-20 on early Fits; check the oil filler cap or owner's manual). PCV system cleaning with Seafoam ($10-15) can help reduce consumption. If out of warranty and severe: engine rebuild ($2,000-3,000).

Owner tips & cautions
- WarningOil monitoring is MANDATORY - check dipstick every 500-1,000 miles, never let oil drop more than 1 quart low
- TipPerform regular PCV cleaning with Seafoam ($10-15) to prevent sludge buildup that worsens oil consumption
- TipHonda extended warranty may cover excessive consumption - check VIN at dealer if burning over 1qt/1000mi
- TipSome owners report oil consumption stabilizes after 50,000 miles - monitor closely during break-in period

Frequently asked questions
What does P052E mean on a Honda?
P052E stands for "Positive Crankcase Ventilation Regulator Valve Performance." P052E indicates a performance problem with the positive crankcase ventilation (PCV) regulator valve, the valve that meters blow-by gases from the engine crankcase back into the intake to be burned. The computer monitors crankcase pressure or related readings, and when the PCV regulator isn't controlling flow within the expected range, it sets this code. Symptoms can include rough idle, oil leaks from seals due to pressure imbalance, whistling/sucking noises, or increased oil consumption. It points to the PCV valve or ventilation system rather than the fuel or ignition system. On Honda it is documented across 1 model: Fit.
What are the most common causes of P052E?
The most common causes of P052E are: Stuck, clogged, or failed PCV regulator valve, Cracked or disconnected PCV hose/line, Vacuum leak in the crankcase ventilation system, Clogged PCV passages from sludge or carbon, Faulty crankcase pressure sensor, Damaged valve cover with integrated PCV (where applicable), Wiring or connector fault on electrically controlled PCV valves. The specific cause varies by vehicle.
How much does it cost to fix P052E on a Honda?
Repair costs vary widely with the root cause and Honda model; each issue on this page carries its own estimate where one is published.
