P0016 on Toyota
Crankshaft/Camshaft Position Correlation - Bank 1 Sensor A
P0016 on Toyota vehicles indicates crankshaft/camshaft position correlation - bank 1 sensor a. Au7o has documented this code across 5 Toyota models — most commonly on Camry, Corolla, Land Cruiser. P0016 means the engine computer found that the crankshaft and camshaft position sensors on Bank 1 (Sensor A) are not lining up the way they should — the timing 'correlation' between them is out of range. These two sensors tell the computer where the pistons and valves are so it can time fuel injection and spark precisely. When their signals don't agree within tolerance, the computer sets this code. It generally indicates an engine timing issue, which may be a worn timing chain, a sticking variable valve timing component, or a sensor problem, and can cause rough running, hard starting, or potential engine damage if ignored. Typical repair costs on Toyota range from $80 to $2,500, depending on the specific model and root cause.
Common Causes of P0016
- •Stretched timing chain or worn timing components (guides/tensioner)
- •Faulty camshaft position sensor or crankshaft position sensor
- •Stuck or faulty variable valve timing (VVT/VCT) actuator or solenoid
- •Low or dirty engine oil affecting the VVT actuator
- •Clogged oil control valve or restricted oil passages
- •Timing chain/belt installed one tooth off after service
- •Damaged reluctor/tone ring on the crankshaft or camshaft
- •Wiring or connector faults at the position sensors
P0016 on Toyota by Model
Toyota Camry(1 issue)
- 2005-2007 VVT-i Actuator DTC Verification - T-SB-0269-102005-2007
Toyota T-SB-0269-10 applies to certain 2005-2007 Camry vehicles equipped with the 2AZ-FE and produced before bulletin-specific VIN gates. The covered condition is MIL illumination with P0011, P0012 or P0016; Toyota says the VVT-i actuator may be the cause in some cases and supplies a test to verify actuator operation. The bulletin does not establish a clogged oil-control valve as the near-universal cause, does not apply to 2AR-FE or A25A-FKS Camrys, and does not make any one DTC a parts diagnosis.
Toyota Corolla(2 issues)
- Timing Chain Tensioner Wear Causing Cold-Start Rattle (1ZZ-FE/2ZR-FE)1998-2012
Chain-driven 1ZZ-FE (and early 2ZR-FE) Corollas commonly develop a brief rattle/chatter from the timing-chain area for the first few seconds after a cold start. The hydraulic chain tensioner relies on oil pressure to take up slack; with age, sludge/varnish buildup in the tensioner or a worn tensioner/guides lets the chain slap until oil pressure builds. It is a heavily discussed issue on owner forums (ToyotaNation, BobIsTheOilGuy, CorollaForum). Usually it's a benign-but-annoying noise, but a badly worn tensioner/guides can eventually let the chain wear the cover or, in severe cases, jump timing.
- VVT-i Camshaft Timing Oil Control Valve Failure Causing P0011 and Rough Running2000-2010
The VVT-i camshaft timing oil control valve (OCV/spool valve, PN 15330-22030 on 1ZZ-FE) sticks or clogs with oil varnish on high-mileage Corollas, so the intake cam phaser can no longer be controlled. This sets P0011 'A Camshaft Position Timing Over-Advanced (Bank 1)' (or P0010/P0016) and can cause rough idle, hesitation and a rattle at start. Low or dirty engine oil, and the small OCV filter screen clogging, are the usual root causes.
Toyota Land Cruiser(2 issues)
- Timing Belt Tensioner and Water Pump Failure (2UZ-FE)1998-2007
The 2UZ-FE 4.7L V8 uses a timing belt that must be replaced at 90,000-mile intervals. The hydraulic timing belt tensioner and idler pulleys are critical failure points — if the tensioner fails, the timing belt can slip or break, potentially causing valve-to-piston contact on this interference engine. The water pump is driven by the timing belt and commonly leaks at the same mileage interval. Since the labor to access the timing belt is 6-8 hours, all components (belt, tensioner, idler pulleys, water pump) should be replaced together as a comprehensive timing belt service.
- 2UZ-FE 4.7L V8 timing belt / water pump 90k service (100-series)1998-1999
The 1998-1999 100-series (UZJ100) switched to the 4.7L 2UZ-FE V8, which uses a rubber timing belt on a ~90,000-mile replacement interval. The timing-belt-driven water pump, the hydraulic tensioner, and the idler pulleys are the common failure points and are typically leaking or worn by that interval (water-pump failure often precedes belt wear). There is a long-running interference vs. non-interference debate: Toyota officially lists it as interference, but the community consensus (and documented belt breaks on the early non-VVT-i 2UZ-FE) is that it generally does not bend valves when a belt snaps at low RPM. Regardless, a broken belt strands the vehicle, and careless belt jobs can nick the crank sensor reluctor wheel or pinch/route wiring wrong, causing no-start or timing DTCs.
Toyota Tacoma(1 issue)
- P0016 — Bank 1 Crank/Cam Correlation Fault from Stretched Timing Chain or VVT-iW Actuator (3.5L 2GR-FKS)2016-2023
On the 3rd-gen Tacoma's 3.5L 2GR-FKS (2016+), P0016 means the ECM sees the Bank 1 intake camshaft position out of correlation with the crankshaft. Unlike the OCV-driven P0011, P0016 more often reflects a mechanical timing error — a slightly stretched timing chain or a worn/sticking VVT-iW cam timing gear (actuator) in the cam hub — or the system's well-known sensitivity to oil condition. The 2GR-FKS VVT-iW (wide-authority) system uses high oil pressure through cam-hub actuators, so low, aged, or wrong-viscosity oil, or a clogged oil-control-valve filter screen, can starve the actuator and throw a correlation code. It commonly appears alongside cold-start rattle and sometimes P0011/P0012/P0021/P0022.
Toyota Tundra(1 issue)
- VVT-i Intake Cam Gear Cold-Start Rattle2007-2013
Tundras with Toyota's VVT-i system can produce a brief (~1 second) rattle or knock at cold start. The cause is the intake-side VVT 'cam gear' (variable cam timing actuator): when oil drains back out of the VVT unit overnight, the lock pin is disengaged and the internal components impact the housing during initial cranking before oil pressure refills the unit. Toyota addressed the condition with TSBs and revised cam-gear/actuator designs on affected engines. While brief rattle is usually benign, severe cases can let the VVT housing and sprocket separate, causing the engine to stop.
