Parts for your 2022 Mitsubishi Eclipse cross-Temperature sensors

2022 Mitsubishi Eclipse Cross temperature sensors

Temperature sensors are absolutely fitted to the 2022 Mitsubishi Eclipse Cross. Technical sources including the Mitsubishi Motors Service Manual for the Eclipse Cross (engine control, cooling and HVAC sections), the Mitsubishi electronic parts catalogue (ASA), and the model’s OBD-II diagnostic information (DTCs such as P0117/P0118 for Engine Coolant Temperature, P0112/P0113 for Intake Air Temperature, and P0071/P0072 for Ambient Temperature) identify multiple temperature sensors used across the vehicle’s powertrain and climate systems.

On this model, temperature sensors handle critical jobs: the engine coolant temperature (ECT) sensor feeds the ECU for fuelling, ignition timing and radiator fan control, the intake air temperature (IAT) sensor helps the turbocharged 1.5L petrol engine manage mixture and knock resistance, the ambient air temperature and evaporator sensors help the HVAC deliver accurate cabin comfort and prevent evaporator icing, and the CVT (where fitted) relies on fluid temperature sensing to protect the transmission and adjust line pressure and shift strategy. These components work together to keep the Eclipse Cross running sweetly and efficiently in Aussie and Kiwi conditions.

They’re not usually a routine replacement item, but they do benefit from sensible servicing checks:

• Look for symptoms: hard cold starts, rough idle, rich running, poor fuel economy, temp gauge misbehaviour, radiator fans stuck on, A/C cycling oddly, or CVT overheat warnings. A scan tool showing implausible temperature readings is a giveaway.
• Inspect connectors and looms. Heat, road grime and moisture can cause corrosion or broken wiring, especially near the radiator support (ambient sensor) and thermostat housing (ECT).
• Service the cooling system as per the owner’s manual—fresh, correct-spec coolant protects the ECT sensor and helps the ECU read accurately. Always bleed air after cooling work.
• When replacing sensors, use OE-spec parts with the right seals, fit only on a cold engine where applicable, and torque to the service manual spec. Many ECT sensors have pre-applied sealant, avoid extra tape unless the manual specifies it.
• CVT fluid temperature sensing may be internal to the transmission assembly—diagnosis or replacement is best left to a transmission specialist.

After any sensor replacement, clear fault codes and verify live-data temperatures from a cold start to operating temp. No special coding is typically required, but confirming stable readings and proper fan/A/C behaviour is smart. Keeping these small sensors healthy helps the 2022 Eclipse Cross deliver reliable performance, good fuel economy and comfy cabin temps on every trip.

What are common signs a coolant temperature sensor is failing on a 2022 Eclipse Cross?

Watch for long cranking when cold, high or hunting idle, black exhaust smoke, heavy fuel use, cooling fans running constantly, or a dash temp reading that doesn’t make sense. A scan tool showing a stone-cold or wildly hot coolant value after an overnight park is another strong clue.

Do temperature sensors need routine replacement?

No, not on a fixed schedule. They’re replaced when faulty or contaminated. Prioritise good coolant, clean connectors and periodic scan checks. If a DTC points to ECT, IAT or ambient temp sensor faults—and wiring checks out—fit a quality OE-spec sensor.

Is it OK to keep driving with a dodgy temp sensor?

Best not. A bad ECT or IAT can push the engine rich, raise emissions, and risk overheating or turbo protection cutbacks. A failed HVAC or ambient sensor mainly affects comfort, but a CVT temp issue can trigger limp mode. Sort it promptly to avoid bigger bills.
