Smart aleky answer: Yes. You manually plug in the OBD II code reader into the port under the dash and manually read the problem displayed on the screen. If, by "manually" you mean the pre OBD II days where you jumpered a connection and watched a light flash on the dash the answer is, unfortunately, no. Systems have become far too sophisticated and you'd be counting Morse Code type long and short flashes for hours trying to figure out what the computer is trying to tell you. The good news is, OBD II readers are loaned free by many auto supply stores. In many cases you can grab the reader, plug it in in the store parking lot, read the code and walk right back in to purchase the appropriate part (which is why they loan you the gizmo for free).

Can you check Toyota check engine codes without special tools?
Depends on the year...if it's an OBD1 car (typically before 1996) you can manually access the codes and find out what they are by watching the "check engine" light blink. If it's an OBD2 car, then no...you have to have a code reader. The good news is that many auto parts stores will read the codes for you for free. Just be careful listening to their diagnosis.
Why does 1999 Toyota solara Traction off light on dash stays on?
The traction off light on a 1999 Toyota Solara may stay on due to several reasons, such as a malfunctioning traction control system, a faulty wheel speed sensor, or issues with the brake system. It could also indicate that the system has been manually disabled. To diagnose the problem accurately, it's best to scan for error codes using an OBD-II scanner and inspect the relevant components. If needed, consult a professional mechanic for further evaluation and repair.

What causes the check engine light to come on for a Toyota Camry 1991?
The ECM (computer) does self tests of components while the car is running or driving. It will turn on the light when it finds a component that is out of the specified range of operation. Scan it or retrieve the codes manually to see where the problem lies.

Where do you find the oxygen sensors in the 2001 six cylinder Toyota Solara and how do you know which one is needing to be replaced?
In the 2001 six-cylinder Toyota Solara, the oxygen sensors are located in the exhaust system: one before the catalytic converter (upstream) and one after it (downstream). To determine which sensor may need replacement, you can check for diagnostic trouble codes (DTCs) using an OBD-II scanner; codes related to oxygen sensor performance issues will indicate a faulty sensor. Additionally, physical inspection for signs of damage or contamination can help identify a failing sensor. If the vehicle exhibits poor fuel economy or rough idling, these may also suggest a malfunctioning oxygen sensor.
