Parts for your 2016 Toyota C-hr-Temperature sensors

2016 Toyota C-HR temperature sensors: what they do, and how to look after them

Based on Toyota’s Repair Manual (RM), Electrical Wiring Diagram (EWD), and the Toyota Electronic Parts Catalogue for the 2016 launch models (NGX10/NGX50 1.2L 8NR‑FTS and ZYX10 Hybrid 2ZR‑FXE), temperature sensors are absolutely fitted to the 2016 Toyota C‑HR. These include the engine coolant temperature (ECT) sensor, intake air temperature (IAT) sensor (integrated with the MAF on many trims), ambient air temperature sensor for the A/C, evaporator temperature sensor, and—depending on spec—the CVT fluid temperature sensor and hybrid battery temperature sensors. In short, temperaturesensors are relevant and used on the 2016 C‑HR.

On this model, temperature sensors help the engine computer and climate systems make smart decisions. The ECT sensor tells the ECU how warm the engine is so it can set fuel, timing, idle speed, and cooling‑fan operation. The IAT helps with fuelling and turbo response on the 1.2T. Ambient and evaporator sensors keep the cabin comfy without fogging the windscreen. CVT fluid temperature data protects the transmission, and hybrid battery temp sensors look after battery life and performance.

While temperaturesensors aren’t usually a scheduled replacement item, they’re frontline for reliability and fuel economy. During regular servicing of a 2016 Toyota C‑HR, it’s worth:

• Scanning live data and checking for DTCs (e.g., P0115 series for ECT).
• Inspecting connectors for corrosion, loose pins, or coolant wicking into the plug.
• Maintaining the cooling system (correct Toyota‑approved coolant, no leaks, healthy radiator and thermostat) so the ECT reads properly.
• Ensuring the MAF/IAT housing is clean—use proper MAF cleaner, never touch the element.
• Confirming the bumper‑mounted ambient sensor isn’t damaged after a minor prang.

Replacement is straightforward when a sensor tests out of spec or throws repeat faults. Use a quality OEM‑equivalent part, fit a new O‑ring or sealing washer where applicable, and tighten to the spec in the Toyota RM. Bleed the cooling system after an ECT swap, clear codes, and verify with a warm‑up and a road test while watching live temps. For the hybrid, leave high‑voltage battery sensor work to trained techs.

Typical warning signs include hard cold starts, high idle that never settles, poor fuel economy, the radiator fan running constantly, erratic A/C temps, or CVT limp‑mode under load. Sorting a dodgy temperaturesensor early can save fuel, reduce emissions, and prevent bigger dramas down the track. If someone’s searching for 2016toyotachr temperaturesensors, they’re looking at a part that genuinely matters for day‑to‑day drivability.

Popular questions about 2016 Toyota C‑HR temperature sensors

Where is the engine coolant temperature sensor on a 2016 Toyota C‑HR?

On the 1.2‑litre turbo (8NR‑FTS), the ECT sensor is threaded into the thermostat housing/coolant outlet near the cylinder head. On the hybrid (2ZR‑FXE), it’s similarly located on the coolant outlet assembly. It’s accessible from the top with the engine cover off, but space can be snug.

Always confirm location in the Toyota RM for the exact VIN, as bracket layouts and hose routing can vary by market and trim.

What are the symptoms of a failing temperature sensor on a 2016 C‑HR?

Common signs include hard cold starts, rich running, poor fuel economy, the cooling fan stuck on, slow warm‑up, or an A/C that can’t hold a steady cabin temp. The MIL may light with codes like P0115–P0119 for the ECT.

If the IAT side is off, expect hesitant throttle and odd turbo response. A scan tool reading that never changes (or is implausible) versus actual engine temp is the giveaway.

Does the 2016 Toyota C‑HR Hybrid have extra temperature sensors?

Yes. Along with engine‑side sensors, the ZYX10 Hybrid uses battery temperature sensors within the HV battery pack to manage cooling and longevity. The HVAC control also relies on evaporator and ambient sensors for efficient climate control.

High‑voltage components should only be checked or replaced by technicians trained in hybrid systems for safety and warranty reasons.
