Ford ranger error p406

https://www.vehiclehistory.com/questions/what-is-the-ford-ranger-radio-code-reset-procedure-135212

When you go to start the vehicle and you turn the key on but not to the start position, all the dash warning lights come on, are they all coming on? IT is very unusual to have a warning chime with no light. I am wondering if a bulb is out in the dash. Or you can go to a store like orielly and have them check the obd codes for free. This will tell you if there is a code stored in the computer showing an error.

Check the On/Off switch on the dash, steering column, and the steering arm/lever is connected properly and that the lighting cable's are cable connectors are connected and not corroded.
1, To check the Earth: Connect a cable from the earth of the bulb to the chassis/body/ metal part of the car.
2, Using a Test lamp: Disconnect the cable that connects the power to the head light bulb, Connect one end of the test lamp to any one of the connectors at the end of the cable that plug's into the bulb. With the low beam on, only one of these wire's will the light switch turned on will light up the test lamp bulb. If none of the cable's light the test lamp bulb. the problem is in the High beam relay, and possibly the Low beam relay as well.
One Head lamp relay: If one cable show a light in the test lamp, check the earth cable on that lamp.
Two Head lamp relay: If two cable's show a light in the test lamp, check the earth cable on that lamp.
Some of the car's electrical systems use the Steering column as an earth point. Check the switch.
In many cases are what is called Earth return (this means that the positive power (+) is supplied by one wire, and the negative earth (-) is connected via another wire) this is to reduce the problems of the rust effecting the power flow.

Sorry I can't be of more help

i would start looking for vacuum leaks first,

You might want to try "google images" just type in your vehicle and what your looking for. Here's an example (link) of what to look for.

You should be showing the check engine light. Rent a scanner, read out any code(s) and pursue to repair(s).

Error codes P1132 and P1152 indicate O2 sensors reading rich at banks 1 and 2. Change O2 sensors.
