Parts for your 2014 Honda Cr-v-Temperature sensors

2014 Honda CR‑V temperature-sensors

Based on Honda’s technical literature, temperature sensors are absolutely relevant and fitted to the 2014 Honda CR‑V. The Honda 2012–2014 CR‑V Service Manual details multiple temperature-dependent systems, including the Engine Coolant Temperature (ECT) sensor(s) used by the PCM, Intake Air Temperature (IAT) sensing for fuelling and ignition, an ambient/evaporator temperature sensor for HVAC performance, and an Automatic Transmission Fluid (ATF) temperature sensor for shift strategy and protection. Honda parts catalogues for 2014 CR‑V variants also list these sensors by part number, and the electrical wiring diagrams show their dedicated circuits. So yes—temperature sensors are very much part of how this CR‑V runs, stays cool, and shifts smoothly.

On a 2014 CR‑V, temperature sensors quietly keep everything in the sweet spot. The ECT sensor feeds the engine computer a live reading of coolant temperature so it can trim fuelling, ignition timing and idle speed, and kick the radiator fans in at the right moment. The IAT sensor lets the car adjust for hot Aussie summers or a chilly Kiwi morning, helping avoid pinging and keeping economy tidy. The ambient and evaporator sensors let the climate control deliver the set cabin temp without fogging or freezing the evaporator. In auto models, the ATF temperature sensor protects the transmission, altering shift timing and line pressure when things get hot under the collar.

They’re not usually “service items”, but they do benefit from a bit of attention during routine servicing:

• Look for tell‑tales: hard cold starts, high idle when warm, poor fuel economy, the temp gauge acting odd, radiator fans running constantly, weak A/C on a hot day, or harsh/late shifts. Common fault codes include P0117, P0118, P0128 (coolant temp), P0112/P0113 (IAT) and P0710/P0711 (ATF temp).
• Inspect connectors and looms for corrosion or brittle insulation—especially the ECT plug near the thermostat housing and the ambient sensor behind the front bumper where road grime collects.
• When changing coolant, check the ECT sensor sealing washer/O‑ring area for weeps. Use Honda Type 2 coolant and bleed air properly to keep readings accurate.
• If replacement is needed, only work on a stone‑cold engine. Depressurise the cooling system, disconnect the battery, unplug the sensor, swap it with a quality OE‑spec part, and tighten to the service‑manual spec. Refill and bleed coolant, then verify operation and clear any stored codes.

The IAT sensor sits in the intake tract and is easy to foul with dust or oil vapour—don’t soak it in harsh cleaners. The ATF temperature sensor lives inside the transmission, diagnosis is by scan data and resistance checks, and replacement typically goes hand‑in‑hand with deeper transmission work. Sticking with genuine or OE‑quality sensors keeps the CR‑V’s behaviour consistent, comfort on point, and the driveline well protected across Aussie and Kiwi conditions.

Popular questions about 2014‑Honda‑CR‑V temperature‑sensors

Where is the engine coolant temperature sensor on a 2014 CR‑V?
The ECT sensor is mounted on the engine near the thermostat housing/cylinder head area, where it can read coolant temp directly. Access is from the top of the engine bay. Always let the engine cool completely before touching cooling system components to avoid burns and false diagnostics.

Do temperature sensors need regular replacement?
Not on a schedule. They’re designed to last the life of the vehicle, but age, heat cycles, coolant contamination, or connector corrosion can tip them over. During regular servicing, a visual check of wiring, a scan for stored codes, and confirming live‑data readings is usually enough. Replace only when testing shows they’re out of spec or causing symptoms.

Can a bad temperature sensor cause poor fuel economy on a 2014 CR‑V?
Yes. If the ECT or IAT sensor reads cold when the engine or intake is actually warm, the PCM enriches the mixture, which burns more fuel and can make the engine feel doughy. A quick scan‑tool check of live temperatures versus actual conditions helps pinpoint if a sensor is fibbing.
