2015 Toyota Fj Cruiser P0121 Fault Code Check
When you check 2015 Toyota Fj Cruiser car engine light came on code P0121 the reason should be Engine Light ON (or Service Engine Soon Warning Light). However Toyota manufacturer may have a different definition for the P0121 OBD-II Diagnostic Powertrain (P) Trouble Code. So you should chech it on our car models.
A good ground connection is also extremely important. P0121 2015 2015 Toyota Fj Cruiser engine problem because the presence of voltage at the panel harness won't make the panel work if there is a bad ground connection. Since the instrument cluster is mounted in a plastic dash, a separate ground wire or ground circuit through the wiring harness is usually needed to complete the power circuit. Refer again to the wiring diagram to find the ground path, and then check it with your ohmmeter. Do not use a self-powered test light because it cannot measure resistance (any resistance will lower circuit voltage).

2015 Toyota Fj Cruiser P0121 Possibble Fix Ways :
Probably the biggest result of injector failure is due to the injectors having excessive return flow or back leakage. This is due to worn parts which allow excessive fuel to go through the diesel injector and to return back to the tank or fuel system. This causes a drop in rail pressure which results in hard starting or not starting at all.
OBD P0121 2015 2015 Toyota Fj Cruiser code and tailpipe testing are two different approaches to identify vehicles in need of repair. The OBD system looks for broken or malfunctioning emissions control components and P0121, while tailpipe tests sample a vehicle's exhaust to see if it is above or below certain prescribed limits. Given the robust nature of today's emissions control components, it is entirely possible for an individual component to P0121 2015 2015 Toyota Fj Cruiser malfunction without leading to an immediate increase in emissions at the tailpipe. In such cases, other components (like the catalyst) can temporarily compensate for the part that is broken however, these other components can only do double duty for so long before they, too, begin to malfunction. In addition, OBD also monitors for P0121 2015 2015 Toyota Fj Cruiser and other malfunctions in the fuel system problems that traditional tailpipe tests were not designed to identify. Most state and local areas also include a gas cap pressure test as part of an emission inspection.
