If your Toyota Camry’s Check Engine Light is on and a scan reveals P1344, you’re seeing a specific signal from the engine control module not just a generic warning. This code points directly to a problem with the camshaft position sensor “A” circuit on bank 1, which in most Camrys means the intake camshaft sensor near the front of the 2.5L 4-cylinder (A25A-FKS) or older 2.4L engines. It matters because this sensor helps time fuel injection and ignition precisely if it fails or sends inconsistent data, you’ll likely notice rough idling, hesitation during acceleration, or even stalling.

What does P1344 mean on a Toyota Camry?

P1344 is an SAE-defined OBD2 trouble code meaning Camshaft Position Sensor “A” Circuit Intermittent Bank 1. On Toyota Camrys, “Bank 1” refers to the cylinder bank containing cylinder #1 always the only bank on 4-cylinder models. “Sensor A” is the intake camshaft position sensor. The word intermittent is key: the issue isn’t constant. The sensor may work fine one moment and drop out the next making it harder to catch with a basic visual check, but easier to confirm with live data using a scanner that reads camshaft position correlation or timing deviation.

When do Camry owners usually see P1344?

You’ll typically get P1344 after noticing drivability issues first like stumbling at low RPM, delayed throttle response, or the engine cutting out briefly when stopping. Some owners report it appears more often when the engine is warm or after short trips where oil hasn’t fully circulated to the VVT-i oil control valve. It’s also common after routine maintenance if the sensor connector wasn’t seated fully, or if oil leaks have contaminated the sensor tip. Unlike some codes, P1344 rarely shows up without symptoms it’s not just a “ghost code.”

What parts are usually involved?

The most common cause is a worn or oil-fouled intake camshaft position sensor. Toyota sensors are known to degrade over time especially past 120,000 miles and oil seepage from the valve cover gasket can coat the sensor tip and disrupt its magnetic reading. Less often, it’s a broken wire, corroded connector, or a stuck VVT-i oil control valve that causes timing shifts large enough to trigger the code. Rarely, it’s internal timing chain stretch but that usually comes with other codes like P0016 or P0017, and noticeable rattle on cold start.

Common mistakes people make diagnosing P1344

• Replacing the sensor without checking the connector for bent pins or oil residue many Camrys have connectors that look fine until you unplug and inspect the terminals closely.
• Assuming it’s the same as a crankshaft position sensor fault these sensors serve different functions and aren’t interchangeable.
• Clearing the code and driving without verifying timing correlation in live data. P1344 can return quickly if the root cause is a clogged oil control valve rather than the sensor itself.
• Using non-OEM sensors. Aftermarket units sometimes lack the proper resistance profile or shielding, leading to intermittent signals under heat or vibration.

How to test before replacing anything

Start by locating the intake camshaft position sensor it’s mounted on the front of the cylinder head, near the timing cover, usually behind the alternator on 2.5L engines. Unplug it and check for oil in the connector cavity. If present, clean it thoroughly with electrical contact cleaner and inspect the valve cover gasket for leaks. Then use a multimeter to test resistance across the sensor’s two terminals: it should read between 800–1,200 ohms at room temperature. If it’s open (infinite resistance) or way off, the sensor is faulty. Also check for continuity between each terminal and ground if either shows continuity, there’s a short in the wiring.

Is P1344 the same across all vehicles?

No the definition of P1344 is standardized, but how it behaves and what triggers it depends heavily on the engine design. For example, on GM V6 engines, P1344 relates to misfire detection in cylinder 4, not camshaft timing. And on the Ford F-150 4.6L, it points to a different camshaft sensor circuit configuration. So while the code number is identical, the repair path for your Camry won’t match those vehicles. That’s why it’s important to reference Camry-specific resources like our detailed breakdown of what P1344 means specifically for Toyota Camry engines.

Next step: What to do right now

Don’t ignore P1344 even if the car seems to run fine today. Intermittent cam sensor faults can worsen without warning, and repeated timing errors may eventually affect catalytic converter efficiency or cause hard starts. Here’s what to do:

1. Check for oil in the sensor connector and clean it if needed.
2. Verify sensor resistance with a multimeter.
3. Scan for related codes P0010, P0011, P0016, or P0300 could point to VVT-i or timing issues instead of just the sensor.
4. If resistance is good and no oil is present, monitor live data for camshaft position correlation (CMP vs. CKP) over several drive cycles.
5. Replace the sensor only if testing confirms failure or if cleaning and reseating doesn’t resolve it within 2–3 days of normal driving.

If you’re working on a different vehicle, you might find helpful context in our guides on P1344 for GM V6 engines or P1344 for the Ford F-150 4.6L but remember, Camry diagnostics follow Toyota’s own system logic.
