Parts for your 2019 Honda Cr-v-Throttle position sensors

2019 Honda CR‑V throttle position sensors (TPS)

Technical sources confirm the 2019 Honda CR‑V does use throttle position sensors. Honda’s Factory Service Manual for the 2017–2019 CR‑V (Electronic Throttle Control System section) and the Honda electronic parts catalogue show the throttle body contains two internal Throttle Position (TP) sensors, often labelled Sensor 1 and Sensor 2, and the accelerator pedal assembly contains two Accelerator Pedal Position (APP) sensors. The TP sensors are non‑serviceable individually, Honda directs replacement of the complete throttle body if a TP sensor is faulty. Relevant OBD‑II DTCs in the Honda service information include TP sensor correlation and range/performance codes such as P0121–P0123, P0221–P0223, and P2135.

On a 2019 CR‑V, the TPS pair constantly reports the throttle plate angle to the powertrain control module (PCM). That live signal helps the PCM manage fuel injection, ignition timing, turbo boost control on the 1.5‑litre, transmission shift behaviour, cruise control and stability/traction systems. The dual‑track design is there for redundancy and safety, the PCM cross‑checks both signals and will drop the vehicle into limp mode if they disagree.

As part of routine servicing, workshops should consider the TPS and throttle body as a single assembly. There’s no set replacement interval, but attention is wise if there’s a rough or hunting idle, hesitation off the mark, erratic revs, a lit MIL, reduced power, or codes listed above. In Australia and New Zealand conditions, throttle body cleaning around 60,000–100,000 kilometres (or sooner in dusty use) helps keep the plate from sticking, which can cause bad TPS readings. Use a proper throttle‑body cleaner and a lint‑free cloth, don’t force the electronic plate by hand.

If a TPS fault is confirmed, the correct fix is typically a new throttle body with a fresh gasket. After refit, the PCM needs an idle/throttle learn procedure using a scan tool or the Honda‑specified warm‑up and idle learn steps so the electronic throttle angles are relearned. Battery disconnects and throttle cleaning can also require this relearn. Always torque fasteners to spec from the service data and check live data for TP Sensor 1/2 agreement during a road test.

• Common signs: surging idle, flat spots on acceleration, harsh shifts, cruise dropping out, MIL on with TP/APP codes.
• Good practice: periodic throttle body inspection/clean, software updates if available, and proper relearn after any related work.

Popular questions

Does the 2019 CR‑V have a throttle position sensor or just a pedal sensor?
It has both. The throttle body contains dual TP sensors that report throttle plate angle, and the accelerator pedal module contains dual APP sensors that report pedal input. The PCM compares them for accuracy and safety.

Can the TPS be replaced on its own on a 2019 CR‑V?
No. Honda integrates the TP sensors into the electronic throttle body. If a TP sensor fails testing or sets correlation/range codes, the service procedure is to replace the throttle body assembly and perform an idle/throttle relearn.

Is TPS maintenance part of regular servicing?
There’s no scheduled TPS replacement. However, cleaning the throttle body and checking live TP data during major services (especially in dusty or urban stop‑start use) helps prevent sticky throttle behaviour and nuisance faults.
