- [hilux kun26r p0093 fuel leak code](https://aussiecarfaults.com/hilux-kun26r-p0093-fuel-leak-code/): The Hilux KUN26R P0093 code means the engine computer has detected a fuel pressure drop that suggests a large leak.
- [hilux kun26r p0089 scv fault](https://aussiecarfaults.com/hilux-kun26r-p0089-scv-fault/): On a Toyota Hilux KUN26R with the 1KD-FTV diesel engine, P0089 signals a fuel pressure control problem, with the suction control valve (SCV) a common suspect.
- [ford ranger px2 p2002 dpf efficiency](https://aussiecarfaults.com/ford-ranger-px2-p2002-dpf-efficiency/): Code P2002 on a diesel Ford Ranger PX2 means its engine computer has detected diesel particulate filter (DPF) efficiency below the required level.
- [ford ranger px2 p2458 dpf regen fault](https://aussiecarfaults.com/ford-ranger-px2-p2458-dpf-regen-fault/): On a Ford Ranger PX2 diesel, P2458 means the engine computer has detected a DPF regeneration cycle taking too long.
- [ford ranger px2 p2463 dpf full](https://aussiecarfaults.com/ford-ranger-px2-p2463-dpf-full/): A Ford Ranger PX2 with code P2463 has detected excess soot in its diesel particulate filter (DPF), which traps soot from the exhaust.
- [ford ranger px2 p0401 egr fault](https://aussiecarfaults.com/ford-ranger-px2-p0401-egr-fault/): A Ford Ranger PX2 with code P0401 has detected insufficient exhaust gas recirculation (EGR) flow.
- [ford ranger px2 p0234 turbo overboost](https://aussiecarfaults.com/ford-ranger-px2-p0234-turbo-overboost/): A Ford Ranger PX2 records fault code P0234 when its engine computer detects excessive turbo boost pressure.
- [ford ranger px2 p0299 turbo underboost](https://aussiecarfaults.com/ford-ranger-px2-p0299-turbo-underboost/): P0299 on a Ford Ranger PX2 means the engine computer has detected lower turbo boost pressure than expected.
- [hilux gun126r p0113 intake air sensor](https://aussiecarfaults.com/hilux-gun126r-p0113-intake-air-sensor/): On a Toyota Hilux GUN126R, P0113 means the engine computer has detected a high voltage signal from the intake air temperature sensor circuit.
- [hilux gun126r rising engine oil level dpf](https://aussiecarfaults.com/hilux-gun126r-rising-engine-oil-level-dpf/): A rising engine oil level in a Hilux GUN126R can signal diesel fuel contamination and needs prompt diagnosis.
- [hilux gun126r p0101 maf fault](https://aussiecarfaults.com/hilux-gun126r-p0101-maf-fault/): A Toyota Hilux GUN126R logs P0101 when its mass air flow (MAF) sensor reading falls outside the engine computer’s expected range.
- [hilux gun126r p2458 dpf regen duration](https://aussiecarfaults.com/hilux-gun126r-p2458-dpf-regen-duration/): On a Toyota HiLux GUN126R, P2458 means the engine computer detected that DPF regeneration did not finish within the expected time.
- [hilux gun126r p0401 egr fault](https://aussiecarfaults.com/hilux-gun126r-p0401-egr-fault/): A P0401 fault on a Toyota HiLux GUN126R means the engine computer has detected insufficient exhaust gas recirculation (EGR) flow.
- [hilux gun126r p2453 dpf pressure sensor](https://aussiecarfaults.com/hilux-gun126r-p2453-dpf-pressure-sensor/): On a Toyota HiLux GUN126R, P2453 means the engine computer has detected an unexpected signal from the DPF pressure sensor.
- [hilux gun126r p2002 dpf efficiency](https://aussiecarfaults.com/hilux-gun126r-p2002-dpf-efficiency/): P2002 on a Toyota HiLux GUN126R means the engine computer has detected diesel particulate filter (DPF) efficiency below the required threshold.
- [hilux gun126r dpf light flashing](https://aussiecarfaults.com/hilux-gun126r-dpf-light-flashing/): A flashing DPF light on a Hilux GUN126R signals a soot build-up or failed filter-cleaning cycle that needs prompt professional attention.
- [Weak Car Air Conditioning: Start With Airflow](https://aussiecarfaults.com/weak-car-air-conditioning-start-with-airflow/): When the vents barely move air during an Australian summer, low refrigerant is not the only possibility. A few observations can help separate an airflow issue from a cooling fault.
- [When the Temperature Gauge Starts Climbing](https://aussiecarfaults.com/when-the-temperature-gauge-starts-climbing/): A rising temperature gauge in traffic on a hot Australian afternoon is a reason to act calmly, not to keep driving and hope it settles. Here is what to do once you are safely stopped.
- [A Slow Start After an Australian Summer](https://aussiecarfaults.com/slow-start-after-australian-summer/): The starter turns over sluggishly after a hot spell, but that does not automatically mean the battery is the only thing at fault. Note when it happens before deciding what to test next.
