Parts for your 2021 Honda Cr-v-Crank angle sensor

2021 Honda CR‑V crank‑angle sensor (crankshaft position sensor) — purpose, care and replacement

Yes, the 2021 Honda CR‑V is fitted with a crank‑angle sensor — Honda labels it the crankshaft position sensor (CKP). This is confirmed in Honda’s factory service information for the 2017–2022 CR‑V (PGM‑FI/engine controls CKP sensor procedures) and the Honda Electronic Parts Catalogue for the 1.5‑litre turbo petrol and hybrid variants, as well as the DTC list that includes CKP‑related fault codes (P0335–P0339). Without this sensor, the ECU can’t accurately manage spark and fuel timing, idle control or start/stop functions.

On the 2021 CR‑V, the CKP reads a toothed wheel on the crankshaft, giving the ECU a live picture of crank angle and speed. That lets the engine fire injectors and ignition at the right moment, stabilise idle, and protect the engine if something’s out of whack. Even the hybrid’s engine management relies on it for smooth starts and synchronisation with the e‑drive system.

It’s not a routine “service item” like filters or plugs, but it does deserve a look during scheduled servicing. A quick visual once‑over can save a headache later, especially if the vehicle sees dusty roads or the odd weep of engine oil.

• What to check: wiring loom condition, connector pins for corrosion, sensor body for impact damage, and any oil leaks tracking onto the sensor or its O‑ring seat.
• Typical symptoms when it’s unhappy: hard starting, random stalling, rough idle, misfires, dead tach, or the MIL with codes such as P0335/P0336.

If replacement’s on the cards, it’s a straightforward job for a competent tech. Battery off, vehicle safely raised, splash shield off, then the CKP — usually held by a single bolt low on the block — can be unplugged and swapped. Always fit a new O‑ring, clean the mating surface, route the harness exactly as per the clips, and torque to Honda’s spec from the service manual. After refitting, clear codes and verify crank/cam correlation with a scan tool. DIYers should avoid forcing the connector or letting grit fall into the sensor bore — that’s how leaks and poor signals start.

Prevention’s better than cure. Keeping the area clean, fixing minor oil seeps promptly, and using quality oil reduces contamination that can interfere with the magnetic pickup. If the dash lights up with a CKP code, don’t keep driving for weeks — intermittent stalls are not a fun surprise at a roundabout.

• Is the CKP the same as a crank‑angle sensor on a 2021 CR‑V?
  Yes. Honda’s documentation calls it the crankshaft position (CKP) sensor, but it performs the crank‑angle sensing function — monitoring crank position and speed so the ECU can time fuel and spark precisely.
• How long does a CKP sensor typically last on a 2021 CR‑V?
  They often last the life of the vehicle. Failures are uncommon and usually tied to heat, oil contamination, impact damage or wiring faults. Regular inspections during servicing help catch issues early.
• Can a bad CKP sensor damage the engine?
  Direct damage is unlikely, but driveability can be unsafe. Misfires, stalling, or no‑start conditions can leave the vehicle stranded. Sorting a CKP fault promptly avoids bigger headaches and keeps the ECU’s timing strategies on point.
