test your brake light switch

code p 0341 refers to camshaft position sensor (CMP) sensor A bank 1--range /performance problem=== causes --insecure sensor/ rotor --- air gap--- wiring ---CMP sensor
you will have 2 camshaft position sensors ( one for each cam shaft but they should be the same unit
the sensor receives an impulse from the rotor on the cam shaft and that impulse has to be within the set parameters in the ECM
the air gap is critical to that impulse

Circuit/System Description
The assist step control module (ASC) controls the running board actuators to extend or retract the running boards. Each actuator consists of an electric motor and a potentiometer. The module supplies a low reference and 10-volt reference source voltage to the potentiometer. The ASC control module monitors the voltage drop across the potentiometer on the position signal circuit. When the actuator shaft rotates, the voltage on the position signal circuit changes. The ASC control module supplies the actuator motor with a 12-volt control circuit and a ground control circuit. The ASC module controls the direction of the actuator by changing the polarity of the control circuits.
You should take this to a ASE certified repair shop that has the diagnostic tools to check for stored DTC'S in the running board control module . A code reader for check engine light codes will not work for this system !
This system can set numerous DTC'S

This would be most likely the sensor.

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/edwy_1a56970cf1ea4620

Bolt locks are pretty cheap and don't usually cost more than $10. You can get a new one.

Hi there:
DTC P0638 - Throttle actuator control range/performance
The engine control module (ECM) opens the throttle blades by applying a pulse width modulated voltage to the throttle valve motor. The ECM reverses the polarity on the throttle valve motor control circuits in order to close the throttle blades. The ECM increases the pulse width as necessary to open the throttle blades. The ECM monitors the throttle position (TP) sensors 1 and 2 to determine the actual blade position. If the ECM detects the required pulse width modulation (PWM) to move the throttle blade exceeds a predetermined value, DTC P0638 sets.

According with recalls...
REPAIR ACTION:
* Replace the Throttle Position Sensor (TPS)
* Perform the ECM software update.

NOTE :Always perform a GDS ECM Update by Automatic Mode first as it performs error checking to ensure the correct data is flashed into the vehicle. Always select the latest available ECM Update event data at time of your update.

Hi. Have you fixed it? We have the same problem. Thanks.

(CF30) - Reference plate detection voltage abnormality: The output
value of the color auto-toner sensor against the reference plate
is out of a specified range at the light amount correction during
an auto-toner adjustment or when a print job has finished.

Your color auto-toner sensor and reference plate are located under the input tray cover on the left side of the copier when you are facing it. It is on a bracket that hangs down into the copier and sits close to the revolver inside the machine. It is an optical sensor and if either it or the reference plate get stained with toner it will give you this error message, you may attempt to clean them with rubbing alcohol.

This error message may also occur if the solenoid that drives the reference plate is faulty so you will need to check that as well.

I would sincerely recommend that you get an authorized toshiba technician to take a look at the machine for you as this is a fairly difficult problem to fix right.

the problems are :-

• cartridges are not recognised or installed
• there is a paper jam.
