Two distinct tick patterns affect 5.0L Coyote V8 in 2015-2023 Mustang depending on engine generation. Gen 2 Coyote (2015-2017): light tick at idle and on cold start, commonly attributed to valve lash / lifter operation; generally cosmetic and not associated with engine damage. Gen 3 Coyote (2018-2023): louder, more pronounced tick — same family but Ford changed to plasma transferred wire arc (PTWA) cylinder liners. The tick is increasingly linked to piston slap from clearance issues against the plasma liner, with some confirmed cases of cylinder wall scoring requiring engine replacement under warranty. Direct injection (added on Gen 3 alongside port injection) contributes a separate fainter HPFP tick that is normal. Distinguishing: Gen 2 tick stays constant warm; Gen 3 piston slap diminishes as engine warms but returns under load. Owner forums (Mustang6G, MPR Racing Engines) document the Gen 3 pattern extensively.

Common Symptoms

  • Tick or tap noise at idle
  • Typewriter-like clicking sound
  • Metallic rattle on cold start
  • Noise that diminishes when warm
  • Ticking more pronounced after oil change

How to Fix

Ford TSB 14-0156 addresses this as a normal characteristic, stating no repair should be attempted. Using Ford's recommended oil (Motorcraft 5W-20 or 5W-30) and changing oil at 5,000-mile intervals may help. For persistent issues, VCT solenoid replacement ($200-400) or cam phaser service ($1,500-3,000) may help.

Multiple factors cause sudden engine stalling including low oil levels (2.4L), VVT issues, faulty sensors, fuel system problems, and transmission-related stalling (2019 9-speed). Stalling typically emerges after ~1,000 miles.

Common Symptoms

  • Engine stalls during turns
  • Sudden stalling at idle or low speed
  • Misfires leading to stalling
  • Engine cuts out without warning
  • Difficult restart after stalling

How to Fix

Diagnosis required to identify root cause: check oil level (especially 2.4L), test MAF and throttle position sensors, inspect VVT system, check fuel pump pressure, verify transmission software updates applied.

Owner tips & cautions

  • WarningFor 2.4L engines: Check oil level weekly - stalling often due to low oil
  • TipDocument stalling incidents with date, mileage, conditions for warranty

The 3.5L 2GR-FE V6 commonly develops oil leaks from the VVT-i oil line, timing cover, and valve cover gaskets. The VVT-i oil hose fitting loosens over time, dripping oil onto the exhaust manifold creating a burning smell and fire risk.

Common Symptoms

  • Burning oil smell from engine bay
  • Oil drips on driveway
  • Oil on exhaust manifold
  • Low oil level between changes
  • Smoke from engine compartment

How to Fix

Tighten or replace VVT-i oil line and sealing washers (Toyota 15679-31010). Replace valve cover gaskets (Toyota 11213-31040 front, 11214-31030 rear). Timing cover reseal if leaking from that area. The VVT-i line fix is a $50 repair; valve cover gaskets run $300-600 due to rear cover access.

The exhaust-side VVT actuator (cam phaser) fails due to oil sludge and wear, causing timing codes and engine rattle. The actuator solenoid can also stick, leading to incorrect valve timing. Oil change neglect accelerates failure. Common on both MZR and early SkyActiv 2.5L engines.

Common Symptoms

  • Rattling noise on cold start (chain slap)
  • Check engine light with P0012 or P0022 cam timing codes
  • Rough idle and stalling at stop lights
  • Reduced power and poor fuel economy

How to Fix

Replace VVT actuator/cam phaser assembly and VVT solenoid. Use Mazda-spec 0W-20 full synthetic oil and replace at 5,000-mile intervals to prevent sludge. Check timing chain stretch while servicing.

The 5.0L Coyote V8 can develop a ticking or rattling noise at startup, often from the cam phasers. This is similar to issues in the Mustang GT. The noise typically diminishes after the engine warms up but can indicate phaser wear.

Common Symptoms

  • Ticking noise at cold startup
  • Rattle from top of engine
  • Noise diminishes when warm
  • Louder in cold weather
  • Check engine light in severe cases

How to Fix

Use quality synthetic oil and change regularly. Ford updated cam phaser design for later production. If noise is excessive, cam phaser replacement may be needed. Check for TSBs specific to your build date.

P0022 code reference

General diagnostic-code context. The code alone does not confirm a cause for your vehicle; use the applicable issue card and its sources.

Frequently asked questions

What does P0022 mean?

P0022 stands for "Intake Camshaft Position Timing - Over-Retarded (Bank 2)." This code means the engine computer found that the intake camshaft on bank 2 is timed too far retarded — more delayed than it commanded through the variable valve timing (VVT) system. The computer adjusts cam timing using an oil-controlled actuator (a phaser) and an electric solenoid, then verifies the cam actually moved to the target position. When the intake cam on bank 2 lags behind its commanded position, this code sets, often causing rough idle, reduced power, or lower fuel economy. (Bank 2 is the cylinder bank that does not contain cylinder 1.) It usually traces back to oil flow, the VVT solenoid, or the phaser.

What are the most common causes of P0022?

The most common causes of P0022 are: Low or dirty engine oil restricting VVT operation, Stuck or clogged camshaft (VVT) oil control solenoid, Clogged VVT oil passages or screen, Worn camshaft phaser/actuator on bank 2, Stretched or worn timing chain affecting cam timing, Electrical fault in the VVT solenoid wiring or connector, Incorrect oil viscosity or overdue oil change. The specific cause varies by vehicle.

How much does it cost to fix P0022?

Repair costs for P0022 range from $50 to $32,000, depending on the vehicle and root cause.

Which vehicles are affected by P0022?

Au7o has documented P0022 across 18 vehicle models from 8 manufacturers: BMW, Dodge, Ford, Jeep, Kia, Mazda, Subaru, Toyota.
