Even if TS has an OBD code reader he has to know how to interpret the fault code. 

Sometimes it takes experience to know what triggered the fault code or codes. It might not be as straightforward as what the fault code tells you.

Newer obd II sends out code and also a brief analysis.

Simplest is try to do a “reset” by unplugging battery connectivity and wait a while before connecting back, or other methods specific to Nissan vehicles. If CEL is still on and still encounter same problems, call for tow truck and send to agent/workshop.

I encountered before and had to tow my Sunny to WS.

Faulty throttle something, cannot remember. WS had to source from scrape yard a replacement but the 2nd hand part conked out within a week. WS replaced it again, this time FOC but after a long wait as part was hard to come by. In the end, we decided to ditch our 11 yo Nissan Sunny ...... sad lor.

That's not what I'm trying to say.

I give an example that is not related to TS issue.

Sometimes a loose vacuum hose or a loose connection may trigger several fault codes. It might not be a part's problem, or sensor problem. Not every car part has a sensor attached to it so this is what I meant by not as straightforward as what the fault codes tells you. 

Not that easy lah. Otherwise your mechanic jiak sai already.

I dunno whether the Sunny(which year which model) throttle body is the electronic controlled or the cable controlled.

For cable usually the wire cable has stretched over time, that can be easily rectified. For the electronic controlled is replacing the sensor attached to the throttle body. Now all the new cars are electronically controlled.

not necessarily. cannot accelerate is limp home mode. everything is cut back. can be coils, throttle body. unlikely fuel pump as my experience with fuel pumps so far, is they are either working or not.
