Parts for your 2016 Ford Ranger-Temperature sensors

2016 Ford Ranger temperature sensors

According to Ford’s technical literature for the Ranger T6 platform (PX/PXII, 2015–2018)—including the Workshop Manual sections for Electronic Engine Controls and Diesel Aftertreatment, plus the factory wiring diagrams—the 2016 Ford Ranger is fitted with multiple temperature sensors. These include the engine coolant temperature (ECT) sensor, intake air temperature (IAT) sensor, ambient air temperature sensor (HVAC), transmission fluid temperature sensor (auto models), and several exhaust gas temperature (EGT) sensors on diesel variants for DPF control. Common OBD-II diagnostics (e.g., P0116/P0117/P0118 for ECT, P0073 for ambient, P242A/P2033 for EGT) further confirm their use on this model.

On the 2016 Ford Ranger, temperature sensors do a heap of behind-the-scenes work to keep the ute healthy and efficient. The ECT sensor tells the PCM how warm the engine is, so it can set cold-start fuelling, ignition timing, and when to switch the electric cooling fan. The IAT sensor helps fine-tune air–fuel mix as intake temps swing with Aussie and Kiwi weather, towing, or altitude. Ambient air temperature feeds the HVAC so climate control behaves properly under the bonnet and in the cabin.

Diesel Rangers rely on multiple EGT sensors before and after the DPF to manage regen accurately and protect the turbo and aftertreatment hardware. On autos, the transmission fluid temperature sensor helps the TCM choose shift strategy and lock-up timing, especially when working hard or hauling. All up, these sensors let the Ranger balance performance, emissions, reliability, and fuel economy across thousands of kilometres.

There’s no fixed replacement interval for temperature sensors, but they’re well worth a look during scheduled services. A quick scan with a proper diagnostic tool to compare live data (cold and hot) is the smart play. Check connectors and looms for heat damage, oil wicking, or rubbed insulation—particularly around the thermostat housing, along the exhaust for EGTs, and near the radiator support for ambient sensors. Healthy coolant and correct mix protect the ECT’s tip and the housing it sits in.

If replacement’s needed, let the engine cool, relieve pressure, and be ready to catch a bit of coolant on ECT jobs. Fit OE-quality parts, torque to spec, and avoid sealants unless the manual calls for them. After refilling, bleed the cooling system, clear any fault codes, and verify readings at operating temp. Typical red flags include high fan speed all the time, hard cold starts, rich running, poor economy, DPF regens failing to complete, or a MIL with temperature-related codes.

• Watch for erratic gauge behaviour or sudden spikes/drops.
• Inspect heat shields and clips around EGT wiring after exhaust work.
• Don’t guess—validate with scan data against an external thermometer where possible.

Popular questions

How many temperature sensors does a 2016 Ranger have?
Most 2016 Rangers have at least an ECT, IAT, and ambient air temperature sensor. Diesel models add multiple EGT sensors around the DPF, and autos include a transmission fluid temperature sensor. Exact count varies by engine and trim, but five to seven isn’t unusual on diesel autos.

What are the signs a temperature sensor is failing?
Look for poor cold starts, rough idle, overactive radiator fan, air-con not behaving, DPF regens not completing, higher fuel use, or the MIL on with temperature-related codes. Live data that doesn’t match reality (e.g., cold engine reading hot) is a giveaway.

Can it be driven with a dodgy temperature sensor?
It might run, but it’s not a good idea. The PCM can default to safe maps that hurt fuel economy and power, and prolonged driving can risk overheating or DPF issues. Best to diagnose promptly and sort the sensor before racking up more kilometres.
