P0345 on a 2022 Toyota Camry

Camshaft Position Sensor Circuit (Bank 2)

P0345 on a 2022 Toyota Camry indicates camshaft position sensor circuit (bank 2). It usually stays drivable short-term but should be diagnosed promptly. The most common cause is failed bank 2 camshaft position sensor (typically $100–$400). Confirm the root cause before replacing parts.

What does P0345 mean on a 2022 Toyota Camry?

P0345 is the Bank 2 counterpart of P0340. The ECM cannot interpret the camshaft position sensor signal on the Bank 2 "A" camshaft — the signal is missing, out of phase with the crankshaft signal, or carrying electrical noise. Bank 2 is the cylinder bank that does NOT contain cylinder number 1, so P0345 only appears on engines with two banks: V6, V8, V10, V12, and flat / boxer layouts. An inline engine has a single bank and cannot set this code.

The symptoms, causes, and diagnostic steps below describe P0345 itself, so they read the same on nearby Toyota Camry model years. Powertrain and trim details vary year to year — confirm the specifics against your own vehicle before buying parts.

Cause Likelihood Estimated repair (USD)
Failed Bank 2 camshaft position sensor Most common $100–$400
Damaged or corroded Bank 2 sensor connector Common $50–$250
Chafed or broken Bank 2 sensor wiring Common $80–$350
Oil leaking into the cam sensor port through a failed o-ring Common $80–$350
Loose, slipped, or damaged Bank 2 camshaft reluctor wheel Occasional $300–$1,200
Timing chain stretch on the Bank 2 side causing cam-crank correlation drift Occasional $800–$3,000
Failed PCM input for the Bank 2 cam sensor circuit Rare $400–$1,500

Cost ranges are editorial estimates for parts and labor at an independent U.S. shop — not quotes. What you actually pay moves with your region, the shop's hourly rate, which engine you have, and how much diagnostic time the job takes. Dealer service departments typically sit above these ranges.

How to diagnose this on a 2022 Toyota Camry

  1. Identify which bank is Bank 2 on this engine

    Bank 2 is the bank without cylinder number 1. On a transverse V6 that is usually the bank nearest the firewall, but "usually" is not good enough — manufacturers vary, and getting this backwards means replacing a healthy sensor on the wrong side of the engine. Confirm the cylinder numbering in the service information for this specific engine before you buy anything.

    Tools: Vehicle-specific service information

  2. Inspect the connector and wiring

    Unplug the Bank 2 sensor and check for corrosion, bent or pushed back pins, oil in the connector body, and chafing where the harness routes past brackets. On transverse engines the rear-bank harness is the one that gets pinched during other repairs, so look carefully if the engine has had recent work.

    Tools: Connector unlock tool, Flashlight, Inspection mirror

  3. Confirm power and ground at the connector

    Key on with the sensor unplugged, verify the supply voltage the wiring diagram specifies and a clean low-resistance ground path. Missing power or a poor ground produces P0345 with a perfectly good sensor installed, and no amount of parts swapping will fix it.

    Tools: Multimeter, Wiring diagram

  4. Scope or graph the Bank 2 sensor signal

    Capture the signal while cranking or running. The Bank 2 sensor should produce the same clean pattern as Bank 1 — which gives you a free reference waveform on the same engine. Comparing the two banks side by side is the fastest way to confirm one is bad.

    Tools: Oscilloscope, or scan tool with raw sensor PIDs, Back-probe pins

  5. Check cam-crank correlation on the Bank 2 side

    Watch the Bank 2 cam signal against the crank signal in live data. They should hold a fixed relationship. An offset that drifts as RPM rises suggests chain stretch on that bank rather than a sensor fault — and replacing the sensor will not resolve it.

    Tools: Scan tool with dual-PID graphing

How do I fix P0345 on a 2022 Toyota Camry?

Engines in the 2022 Toyota Camry

The 2022 Toyota Camry was offered with the 2.5L 4-cylinder and 3.5L 6-cylinder engines, including a hybrid version. Which one you have changes where P0345 is most likely to originate, so confirm your engine before ordering parts.

Engine data: EPA fueleconomy.gov.

If your engine is an inline-4, this code is not yours

P0345 refers to Bank 2 — the cylinder bank that does not contain cylinder number 1. Engines with a single bank (inline-3, inline-4, inline-5, inline-6) have no Bank 2 and cannot legitimately set this code. If a scan tool reports P0345 on a four-cylinder, the most likely explanations are a generic code lookup table in the tool showing you the wrong description, or a manufacturer-specific code that shares the P0345 number. Check the code against the manufacturer’s own definition before you go looking for a sensor that does not exist.

The free reference waveform

A two-bank engine gives you something a single-bank engine cannot: an identical known-good sensor sitting on the other side of the same engine, running in the same conditions, at the same age. Scope both cam sensors together. If Bank 1’s trace is clean and Bank 2’s is noisy, missing pulses, or flat, you have your answer without needing a service manual waveform to compare against.

Bank 2 access is often the real cost

The part itself is the same price on either bank. The labour frequently is not. On transverse V6s the rear bank sits against the firewall, and reaching its cam sensor can mean removing the intake manifold or lifting the engine on its mounts. Before assuming this is the same job as the Bank 1 sensor you replaced two years ago, look up the labour time for your specific engine — it is a fair question to ask a shop for a quote on even if you would normally do the work yourself.

When P0345 is really a timing chain

On engines with documented chain-stretch histories, a cam sensor code can be the first visible symptom of a chain that has worn past spec. The sensor reports the cam’s position accurately; the cam is simply not where the ECM expects it to be. The tell is cam-crank correlation that drifts as RPM climbs, usually paired with a rattle from the timing cover on cold start. If you see both, replacing the sensor buys you nothing — and a chain that skips a tooth on an interference engine turns a timing job into an engine rebuild.
