P0425 Holden Gts OBD Code

OBD/2 P0425 error code description and symptoms.

HO2S Sensor Circuit Malfunction (HO2S-11) During testing the HO2S Heaters are checked for opens/shorts and excessive current draw.
The test fails when current draw exceeds a calibrated limit and/or an open or short is detected. Short to VPWR in harness or HO2S. Water in harness connector. Open VPWR circuit. Open GND circuit. Low battery voltage. Corrosion or poor mating terminals and wiring Damaged HO2S heater. Damaged PCM.

Circuit High Input codes like P0425 are mostly caused by defective alternators that develop excessive voltages, although there may be other causes as well, such as short circuits that 'leak' current into a particular system from other, unrelated systems that work on higher voltages. Note that in the case of short circuits that leak power into a control circuit, there is likely to be other, seemingly unrelated trouble codes present along with the code(s) being investigated. Diagnosing a 'high input' code will always involve a thorough testing of the charging system as a first step, followed by measures to isolate the system from all other possible sources of power during resistance, continuity, and reference voltage tests.

If your p0425 catalyst temperature sensor circuit bank 1 sensor 1 check engine light is illuminated, it's best to take it in for diagnostic testing, which can feel like a hassle. Because while the lights vary in appearance from vehicle to vehicle, all have the same basic meaning: There's a problem with the car's emissions system. The on-board diagnostics system P0425 and engine control unit are in charge of monitoring a bunch of different p0425 catalyst temperature sensor circuit bank 1 sensor 1, and if they get a reading that's a little out of whack, up pops the check engine light.

Common Causes of Holden Gts P0425 OBD2 Code

A common cause of code P0425 is the failure of P0425 Catalyst Temperature Sensor Circuit Bank 1 Sensor 1, but there are several other possible causes as well, such as ;

Exhaust tube
Erratic camshaft position due to low oil pressure
Fuel filler cap remains open or fails to close
Faulty select solenoid

P0425 is a kind of Powertrain Trouble Code

Powertrain of a modern automobile, comprising engine (with exhaust system), transmission, drive shaft, suspension and the wheels. In a motor vehicle, the term powertrain or powerplant describes the main components that generate power and deliver it to the road surface, water, or air.
