Oct 23, 2013 · If the coil on the fuel injector is good, you should see a resistance somewhere around 12 Ohms. If the coil has burnt out, you will see a reading of 0 Ohms (Short Circuit), or ~ Ohms (Open Circuit). If this is the case, the you will need to replace the fuel injector. Testing the Fuel Injector Wiring.
I moved the injector from cylinder 3 to cylinder 1 and gave it to the customer to see what will happen this time. Yesterday, 02:41 AM. Sensor A of the park pawl has electricial fault, replaced but didnt fix 09-14-2020, 11:36 AM. How to open SelectPTDevice in Xentry Pass Thru? Author: newbi2009.

Jan 12, 2016 · STEP 2C-2: Check for high resistance or an open circuit in the injector solenoid and circuit. Condition: • Turn keyswitch OFF. • Remove the rocker cover. • Disconnect the injector harness from the injector solenoid. Action Specification/Repair Next Step Check for an open circuit. • Measure the resistance between the cylinder
P02F1 cylinder 4 injector circuit range/performance Seems that this model (2009) was recalled (but no one told me) to replace the injectors AND injector electronics (entire ECU for that matter). The problem with the piezo injectors seems to be that there's no diesel return line and the wiring gets all soaked in diesel fuel, causing short circuits.
