Working with the 3S-FE ECU requires attention to detail. Using the 34-22-16 pinout diagram, you can easily troubleshoot injector issues, ignition failures, or sensor failures. Always verify with a multimeter, especially when dealing with older, potentially re-wired vehicles.
| Pin | Wire Color | Signal | Description | |------|------------|--------|-------------------------------| | B1 | G-R | VTA | Throttle position sensor signal | | B2 | G-Y | VS | Air flow meter signal (Karman vortex) | | B3 | G | E2 | Sensor ground | | B4 | B-Y | THW | Engine coolant temp sensor | | B5 | L-B | THA | Intake air temp sensor | | B6 | R-L | KNK | Knock sensor (if equipped) | | B7 | W | OX1 | Oxygen sensor (front) | | B8 | B-W | FC | Fuel pump relay control | | B9 | Y-R | ACT | A/C request signal | | B10 | L-R | M-REL | EFI main relay control |
Signal from the Throttle Position Sensor (TPS) indicating throttle blade angle.
Once you have mapped 5 pins (BATT, E1, THW, STA, #10), compare your findings to generic online 3S-FE PDFs. If they match, the rest of the PDF is likely accurate for your car.
Switched 12V power coming from the EFI main relay. This energizes the ECU when the ignition switch is turned to "ON".
If you are swapping a 3S-FE into a different chassis or a buggy, you only need to wire a fraction of the ECU pins to make the engine start and run perfectly.
Signals like the NE and G distributor lines, as well as the Knock Sensor (KNK) line, use shielded cabling to prevent electromagnetic interference from spark plug wires. Ensure the outer metal shielding braid is grounded only at the ECU side, not at the sensor side.
: Camshaft position signals used to determine cylinder stroke. NE : Crankshaft engine speed signal used to calculate RPM.
A 62-page workshop manual for 3S-FE and 3S-GE Wiring Diagrams provides comprehensive schematics for technical guidance.
The 3S-FE ECU pinout PDF has become a valuable resource for the automotive repair community, and its availability has helped countless mechanics and enthusiasts diagnose and repair issues with the 3S-FE engine.
Typically a 3-plug yellow or grey connector setup (10pin - 18pin - 14pin configuration). Air Metering: Often uses a Vane Air Flow (VAF) meter. Generation 2 & 3 (1993–1997) Found In: Camry (V30/V40), Carina, Corona (T190).
Often used for diagnostic connections (TE1, TE2) and load signals like vehicle lighting or heated windows. Key Terminal Assignments
Monitors the exact position of internal engine components via the Crankshaft and Camshaft Position Sensors to fire the spark plugs accurately. Fuel Delivery:

Review permissions, screenshots, update date, and recent reviews before installing any extension.
Install one extension at a time. Some modify overlapping parts of Canvas and may conflict.
These are independent Chrome Web Store listings, not maintained by Instructure or your school.
Yes, but start with one at a time. Extensions that modify the same parts of Canvas (like the dashboard or sidebar) may conflict. Test each one individually before combining.
All 5 extensions listed on this page are free to install from the Chrome Web Store. Check each store listing for details on any premium features or future pricing changes. 3s-fe ecu pinout pdf
Most work on common Canvas domains, but compatibility depends on your school's configuration. Check each extension's store page for supported domains and known limitations. Working with the 3S-FE ECU requires attention to detail
Canvas Analytics has some overlap with Canvas Chart (both visualize grades) and Canvas GPA Calculator (both do grade calculations). Tasks for Canvas and Canvas Chart both modify the dashboard area, so they may also conflict if used together. Canvas Dark Mode and Canvas GPA Calculator are more isolated — they rarely conflict with other extensions. | Pin | Wire Color | Signal |
No. All extensions listed here are independent projects published on the Chrome Web Store. They are not developed, endorsed, or maintained by Instructure (the company behind Canvas LMS) or any educational institution. Always review permissions and privacy policies before installing.
Canvas occasionally updates its interface, which can break extensions that modify the page. If this happens, check the extension's store page for updates, read recent reviews for reports, or temporarily disable the extension until a fix is released. Extensions with larger user bases and recent updates are generally more likely to be patched quickly.
