Exact manufacturer information
Current service information and owner documentation for the exact year, market, engine, trim, transmission, drivetrain, and installed equipment.
Loading IAR content
IAR records who published a source, when it was retrieved, and what it supports. A reputable source is not permission to apply a fact to every vehicle.
Source quality and vehicle applicability are separate questions. Both must be satisfied before an exact claim is treated as verified.
Current service information and owner documentation for the exact year, market, engine, trim, transmission, drivetrain, and installed equipment.
The issuing standards body is preferred when a code structure, protocol, term, or technical convention is being defined.
Official agencies are used for recall lookup, consumer safety guidance, and regulated-service boundaries.
A repair experience can suggest a test path, but it remains visibly separate from reviewed IAR information until evidence and applicability are checked.
Before using a torque value, fluid, tire pressure, interval, wiring path, part number, programming step, recall, or repair procedure, verify the exact vehicle, market, production date, engine, trim, transmission, drivetrain, and installed equipment in current manufacturer information.
This is the complete current public source register—not a claim that every IAR page is vehicle-specific or fully sourced.
Normative reference for standardized diagnostic trouble code structure and definitions.
Manufacturer quick-reference table hosted in NHTSA's public technical-document archive labels P0111 as Intake Air Temperature Sensor Circuit Range/Performance, P0112 as Intake Air Temperature Sensor Circuit Low Input, and P0113 as Intake Air Temperature Sensor Circuit High Input. IAR uses it only as corroborating public evidence for the generic labels; thresholds, sensor location, wiring, vehicle applicability, and repair procedures are not universal claims.
Government technical appendix containing a table that labels generic P0500 as Vehicle Speed Sensor A. IAR uses it only as corroborating public evidence for the generic label; it does not establish any vehicle's sensor location, wiring, thresholds, calibration, or repair procedure.
Manufacturer quick-reference tables hosted in NHTSA's public technical-document archive list P0501 as Vehicle Speed Sensor A Range/Performance and also list P0502 and P0503 in vehicle-specific DTC tables. IAR uses only the public labels as corroborating evidence; thresholds, vehicle applicability, sensor location, wiring, and repair procedures are not universal claims.
Version-awareness record for the current J2012 Digital Annex release. SAE states the spreadsheet is updated several times annually. IAR uses this record to track standard freshness; it does not imply that inaccessible annex rows were reviewed or that every possible DTC definition is published in IAR.
EPA OBD inspection guidance explaining readiness states such as ready, not ready, and not applicable; common reasons monitors may remain incomplete; and the distinction between readiness and a confirmed emissions malfunction. State inspection acceptance rules and manufacturer drive conditions remain outside this source's universal scope.
Consumer OBD-II overview, including steady and blinking malfunction-indicator guidance.
EPA technical report documenting EVAP OBD leak-detection evaluation and a table of generic EVAP diagnostic trouble code descriptions, including P0440–P0449 and selected P045x/P046x definitions listed in its EVAP DTC table. IAR publishes only definitions it has individually reviewed from that table. It is not a universal vehicle test procedure, pressure specification, or component-replacement guide.
Government vehicle-detail listing used only to verify the U.S. model-year, make, and model identity shown by IAR's 2015 Lexus IS 250 foundational hub. It does not establish engine, trim, transmission, drivetrain, market, production-date, installed-equipment, repair-procedure, part-fitment, specification, or exact VIN applicability.
Government vehicle-detail listing used only to verify the U.S. model-year, make, and model identity shown by IAR's foundational 2011 Honda Odyssey hub. It does not establish engine, trim, transmission, drivetrain, market, production-date, installed-equipment, repair-procedure, part-fitment, specification, or exact VIN applicability.

IAR uses it only for model-level configuration facts explicitly shown across the listed trims, including the 3,471 cc V-6, published power output, and the brochure's trim-specific 5-speed and 6-speed automatic transmission entries. It does not establish a particular VIN's trim, transmission, drivetrain, installed equipment, market, production date, repair procedure, specification, or service applicability.
Government vehicle-detail listing used only to verify the U.S. model-year, make, and model identity shown by IAR's partial 2020 Toyota Camry hub. It does not establish engine, trim, transmission, drivetrain, market, production-date, installed-equipment, repair-procedure, part-fitment, specification, or exact VIN applicability.
Manufacturer product information for the U.S. 2020 Toyota Camry model range. IAR uses it only for the explicitly stated model-range powertrain and gasoline-transmission facts: 2.5-liter four-cylinder, 3.5-liter V-6, Toyota Hybrid System (THS II), and Direct Shift 8-speed automatic on the gasoline variants. It does not establish a particular VIN's engine, trim, drivetrain, installed equipment, market, production date, repair procedure, specification, or service applicability.
Manufacturer product information for the U.S. 2020 Toyota Camry AWD model range. IAR uses it only for the explicitly stated model-year availability of Dynamic Torque Control AWD as a stand-alone option on the LE, XLE, SE, and XSE grades, and the stated 2.5-liter four-cylinder / 8-speed Direct-Shift pairing for Camry AWD. It does not establish a particular VIN's drivetrain, trim, engine, installed equipment, market, production date, repair procedure, specification, or service applicability.
Manufacturer product information for the U.S. 2015 Lexus IS model range. It states that the IS 250 uses a 204-hp 2.5-liter V6 matched to a six-speed automatic and that rear-wheel-drive and all-weather/AWD configurations were offered. IAR uses it only for model-year configuration facts explicitly stated by Lexus. It does not establish the drivetrain or installed equipment of a particular VIN, nor repair procedures, torque values, fluid specifications, part fitment, calibration, or service applicability.
Manufacturer-issued U.S. 2015 Lexus IS 250 / IS 350 Owner’s Manual (OM53C50U), reviewed from an archived mirror that identifies the Lexus manual and links its download to Lexus.com. IAR uses this record only for exact specifications explicitly stated in the manual and preserves model, drivetrain, tire-type, temperature, and reference-capacity qualifiers. It does not establish hidden VIN equipment, repair labor procedure, part fitment, calibration, or applicability to another model year or market.
Manufacturer-issued U.S. 2015 Lexus IS 250 Warranty and Services Guide (document 00505–15WSG-IS250; printed 6/14), reviewed from an archived text mirror. IAR uses this record only for scheduled-maintenance and maintenance-item explanation claims explicitly present in the guide and preserves mileage/time, drivetrain, tire-size, and special-operating-condition qualifiers. It does not establish repair procedures, torque values, part fitment, calibration, or applicability to a different model year, model, or market.
Manufacturer-submitted Part 565 data used for year/make/model catalog suggestions and VIN decoding. A full VIN decode may also return manufacturer-reported configuration context such as engine displacement/cylinders, trim, drive type, and transmission style when NHTSA has those variables. Missing decoded values mean NHTSA has no data for that variable, not that the feature is absent. vPIC data does not establish repair applicability, exact service specifications, part fitment, calibration, or open-recall status.
Current U.S. safety-recall lookup plus NHTSA model-level recall data/API documentation. Model-level records do not establish exact VIN eligibility or open-remedy status.
