P0335 on Cadillac
Crankshaft Position Sensor A Circuit Malfunction
P0335 on Cadillac vehicles indicates crankshaft position sensor a circuit malfunction. Au7o has documented this code across 1 Cadillac model — most commonly on Eldorado. This code means the engine computer has lost or detected a faulty signal from the crankshaft position sensor (sensor A), which tells the computer exactly how fast and in what position the crankshaft is rotating. That signal is essential for timing the spark and fuel injection, so a problem here can cause hard starting, stalling, or a no-start condition. The computer sets this code when the crank sensor signal is missing, erratic, or out of its expected pattern. Causes range from a failed sensor or damaged wiring to a problem with the reluctor (tone) ring the sensor reads. Typical repair costs on Cadillac range from $200 to $500, depending on the specific model and root cause.
Common Causes of P0335
- •Failed crankshaft position sensor
- •Damaged, corroded, or loose sensor wiring/connector
- •Metal debris or oil contamination on the sensor tip
- •Damaged or misaligned reluctor (tone) ring
- •Excessive air gap between sensor and tone ring
- •Wiring shorted or open in the sensor circuit
- •Faulty PCM/ECM (rare)

Cadillac Eldorado(1 issue)
- Crankshaft Position Sensor Failure Causing Intermittent Stalling and No-Start2000-2002
The dual crankshaft position sensors on the 2000-2002 Northstar (which feed the coil-on-plug PCM directly) develop cracked solder joints at an internal resistor, causing intermittent chuggle, stalling while driving, long cranking, or a hot no-start that often resolves once the engine cools. GM ran a voluntary emissions campaign on certain 2000 Eldorado and Seville 4.6L vehicles for this defect, and RepairPal documents it as a top Eldorado driveability problem. Because both sensors live behind the oil filter adapter and fail similarly, the accepted practice is replacing both at once.

What does P0335 mean on Cadillac?▼
P0335 stands for "Crankshaft Position Sensor A Circuit Malfunction." This code means the engine computer has lost or detected a faulty signal from the crankshaft position sensor (sensor A), which tells the computer exactly how fast and in what position the crankshaft is rotating. That signal is essential for timing the spark and fuel injection, so a problem here can cause hard starting, stalling, or a no-start condition. The computer sets this code when the crank sensor signal is missing, erratic, or out of its expected pattern. Causes range from a failed sensor or damaged wiring to a problem with the reluctor (tone) ring the sensor reads. On Cadillac specifically, this code is documented across 1 model.
