What is the P1336 fault code?

When this issue occurs, it means that the position of the crankshaft position sensor in the vehicle has changed, or due to reasons such as ECU replacement, the ECU and the crankshaft position sensor need to be re-learned using a diagnostic tool. This ensures the ECU clearly understands the specific position of the crankshaft's operation, thereby determining the top dead center of each cylinder. 1. The definition of the automotive fault code P1336 is: Crankshaft Position Sensor Target Gear Error Learning. After clearing the fault code, the malfunction indicator light (MIL) will turn off, but it will illuminate again upon the next ignition. Upon inspection, the fault code is still present. If the vehicle is the latest model equipped with an OBD system, this may be due to the lack of gear signal learning. Therefore, the MIL will illuminate after starting the engine, and a P1336 fault code will be stored when checked with a decoder. This issue can only be completely resolved by performing a crankshaft position sensor target gear error learning operation using a decoder. 2. In Chinese, the fault code P1336 means: Crankshaft Position (CKP) Sensor - Signal Scope: The crankshaft converts the up-and-down motion of the pistons into rotational motion. The crankshaft position (CKP) sensor (also known as the top dead center sensor) detects the top dead center (TDC) signal, crankshaft angle signal, and engine speed signal, and inputs them completely into the computer. This allows the computer to issue the optimal ignition timing instructions according to the ignition sequence of the cylinders.
Last time my car threw a P1336 trouble code, which really had me on edge. The check engine light came on, and when I scanned it with an OBD reader, this code popped up. It typically indicates a crankshaft position sensor range issue. This sensor monitors the engine's rotation angle, and if the signal is off, the engine might shake, have difficulty starting, or even stall. Common causes include a dirty or faulty sensor, loose wiring connections, or misaligned engine timing. I tried cleaning the connectors myself, but it didn't help—I ended up replacing the sensor to fix it. It wasn't expensive, just a couple hundred bucks, but if left unchecked, the engine runs rough, fuel consumption spikes, and you might even end up stranded on the roadside. The mechanic said regular checks of the electrical system can prevent issues like this—don't wait until the light comes on to take action. When I encountered this code, I drove slowly to the repair shop immediately—safety first to avoid any accidents.
My old car occasionally throws a P1336 code, causing the engine to sputter unevenly like it's coughing. Online research reveals it's related to a faulty crankshaft position sensor – that tiny component responsible for telling the computer the engine's RPM. Signal errors can mess up ignition timing, leading to stuttering starts or sudden stalls mid-drive. Common culprits include sensor aging, wiring wear, blown fuses, or control module issues. I recall during the last repair, simply replacing the sensor fixed it, costing a few hundred bucks for peace of mind. When encountering this code during daily drives, don't delay – it not only harms the engine but may also increase fuel consumption, making long trips riskier. For DIY checks, start by unplugging the sensor to clean the connectors; simple maintenance saves money and ensures safety. If that doesn't work, seek professional help. After repairs, the engine runs smooth as new, making every drive feel much more secure.
P1336 is a fairly common trouble code, indicating abnormal performance of the crankshaft position sensor. This sensor monitors engine rotation, and weak signals can cause ignition issues. Common causes include sensor damage, loose connectors, or wiring shorts. You can test resistance with tools or read specific data using an OBD scanner. Replacing the sensor is inexpensive, costing just a few dozen dollars if issues are found. When DIY-ing, remember to disconnect power to avoid electric shocks—don't force it. Once fixed, the engine runs smoother, saves fuel, and eliminates worries.
