P2008 identifies Intake Manifold Runner Control Circuit Open Bank 1. Diagnosis compares runner command, actuator current, position feedback, MAP, MAF, rpm, and load so its electrical, control, and physical causes are separated before repair.
P0755 identifies Shift Solenoid B Malfunction. Diagnosis compares Solenoid B command, measured current, commanded gear, turbine speed, output speed, fluid temperature, and ratio so its electrical, control, and physical causes are separated before repair.
P0670 identifies Glow Plug Control Module Control Circuit Malfunction. Diagnosis compares glow request, module status, individual glow current, coolant temperature, supply voltage, and communication state so its electrical, control, and physical causes are separated before repair.
P0605 identifies Internal Control Module Read Only Memory Error. Diagnosis compares module voltage, reset counter, programming history, software identification, network faults, and repeatability so its electrical, control, and physical causes are separated before repair.
P0544 identifies Exhaust Gas Temperature Sensor Circuit Bank 1 Sensor 1. Diagnosis compares exhaust temperature Sensor 1, sensor voltage, engine load, regeneration state, lambda, and harness temperature so its electrical, control, and physical causes are separated before repair.
P0530 identifies A C Refrigerant Pressure Sensor Circuit Malfunction. Diagnosis compares refrigerant pressure, sensor voltage, compressor request, fan request, ambient temperature, and shared reference so its electrical, control, and physical causes are separated before repair.
P0183 identifies Fuel Temperature Sensor A Circuit High Input. Diagnosis compares fuel temperature, sensor voltage, coolant temperature, intake temperature, reference supply, and return-fuel state so its electrical, control, and physical causes are separated before repair.
P0094 identifies Fuel System Leak Detected Small Leak. Diagnosis compares rail-pressure target, measured rail pressure, pump command, pressure decay, trims, and injector correction so its electrical, control, and physical causes are separated before repair.
P2430 identifies Secondary Air Injection System Air Flow Pressure Sensor Circuit Bank 1. Diagnosis compares secondary-air pressure, pump command, valve command, sensor voltage, lambda response, and cold-start time so the failed electrical or mechanical path is isolated before repair.
P2200 identifies NOx Sensor Circuit Bank 1. Diagnosis compares NOx concentration, sensor status, heater current, exhaust temperature, supply voltage, and SCR dosing state so the failed electrical or mechanical path is isolated before repair.
P2015 identifies Intake Manifold Runner Position Sensor Circuit Range Performance Bank 1. Diagnosis compares runner command, position feedback, actuator current, MAP, MAF, engine speed, and calculated load so the failed electrical or mechanical path is isolated before repair.
P0712 identifies Transmission Fluid Temperature Sensor A Circuit Low Input. Diagnosis compares transmission temperature, sensor voltage, engine coolant temperature, ambient temperature, shift state, and EGS supply so the failed electrical or mechanical path is isolated before repair.
