The car needed a new Driver Injector 89871-71010 a new and the diagnostic you talk of from Toyota. Many problems can easily be found in the harness and connectors. Once the code is set, the vehicle will activate its failsafe mode, keeping the engine safe from further damage. Not sure if you have rubber fuel lines or plastic ones. The truck belongs to my neighbor's dad.

Check for presence of battery voltage 12 Volts at one wire of each injector connector. YourMechanic offers certified mobile mechanics who will come to your home or office to diagnose and repair your vehicle. Common Causes The most common cause of this code is damage to wiring caused by wildlife. They light up when the injector is working properly. If you know what causes the problem, you can still decide to do the repair yourself. Specifications on the definition, troubleshooting and repair of the error vary from one make or model to another. There is no better on-line training of how to troubleshoot automotive electrical and electronics systems anywhere! This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.

This video was taken from a 5 part training series I did for my students on various ways to identify a misfire and restricted exhaust testing. This is an advanced strategy best left to professionals. If the injector is open or the resistance is higher or lower than the spec, replace the fuel injector. Other injector circuit fault codes may set as well. A noid light will insert into the injector harness in place of the fuel injector and flash rapidly when the injector driver operates. In either circumstance, it is advised to have professional help as soon as possible to get the vehicle back to its normal operation.

The car will run fine for five ten mins, then It will then lose power and go into limp mode, turning the key off and on again will give full power again for a brief period. Diagnostic test code P0200 given. . When the engine is cranked, the test light should illuminate. If the fuse blows, the last injector you plugged in is shorted.

With the possibility for poor drivability and the engine shutting off and not restarting, this fault should be taken seriously and diagnosed by a quality mechanic as soon as possible. Next, a visual inspection will be performed for the injector circuit looking for any damaged wiring, loose or broken connectors, or components with damage. Not sure if you have rubber fuel lines or plastic ones. Of course checking for a vac leak- old spray trick, If you can scan? The staple symptom, of course, is the illumination of the Check Engine light. Other injector circuit fault codes may set as well. Engine managment is showing up a p0200 code, powertrain - injector control circuit Have checked all connections and all seems good, so signs of leaks either. .

Failsafe is enabled until normal injector operation is found or the fault is repaired. P0202 may also be seen with misfire codes and lean or rich condition codes. To determine if the injectors are restricted, an injector balance test should be performed using a dedicated tester. I sprayed carb cleaner around the intake with no change. But if vehicle starts and maintains 60 psi or more, it's not the pump causing the misfire, if P0200 is a hard code.

I did a fuel pressure test and when I first turn the key on the gauge goes to 60psi and as soon as the pump stops running the pressure drops to 50psi. Electronic fuel injection has been implemented in cars since the 1980s. Was told leak down to zero within 20 minutes is normal, but with a good leak proof system, will hold 50+ psi pressure for over 24 hours. Then, the mechanic will test the injector for voltage to confirm proper operation. If all are missing, check for continuity to ground on the voltage circuit by using a test light connected to positive battery and probe each voltage feed. If the code indeed comes back, the mechanic will proceed on conducting a visual inspection on the injector circuit and the fuel injector itself. So, if you have a cylinder specific injector circuit code, you can skip the second step on the list.

The troubleshooting information listed here can also be applied to codes P0201-P0214. Using the scan tool, test the operation of the fuel injector and check for signs of irregularities. This refers to too high or too low voltage or resistance drop at the injectors. These are used to ensure accurate diagnosis and to avoid guesswork. This light illuminates if the injector is working properly. Noid light are installed to the fuel injector wiring to aid visual inspection of the injector operation.
