MANUAL TRANSAXLE SYSTEM, Diagnostic DTC:P03352A, P033531

DTC Code DTC Name
P03352A Crankshaft Position Sensor "A" Signal Stuck in Range
P033531 Crankshaft Position Sensor "A" No Signal

DESCRIPTION

The crankshaft position sensor system consists of a crankshaft position sensor plate (crankshaft pulley) and Magneto Resistance Element (MRE) type sensor. The crankshaft position sensor plate has 34 teeth at 10° intervals (2 teeth are missing for detecting top dead center), and is installed on the crankshaft. The crankshaft position sensor generates 34 signals per crankshaft revolution. The ECM uses the NE signal to detect the crankshaft position and engine speed.

DTC No. Detection Item DTC Detection Condition Trouble Area MIL Memory Note
P03352A Crankshaft Position Sensor "A" Signal Stuck in Range No crankshaft position sensor signal to ECM while cranking for 4.7 seconds (1 trip detection logic).

  • SFI system

  • ECM

 Does not come on DTC stored

SAE Code:

P0335
P033531 Crankshaft Position Sensor "A" No Signal The 3 seconds after engine started, the engine stalls and the engine speed signal value decreases rapidly (1 trip detection logic).

  • SFI system

  • ECM

 Does not come on DTC stored

SAE Code:

P0335

Tech Tips

When the engine is being stopped or started automatically by stop and start system control, the ECM does not monitor the crankshaft position sensor signal.

MONITOR DESCRIPTION

A DTC will be stored if any of the following occur:

CAUTION / NOTICE / HINT

Tech Tips


  • If no problem is found by this diagnostic troubleshooting procedure, check for problems by referring to the engine mechanical section.

  • Read freeze frame data using the GTS. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.

  • After performing repair, clear the DTCs and perform the following procedure to check that DTCs are not output.


    1. Start the engine and wait for 3 seconds or more.

    2. Check for DTCs again.

  1. DATA LIST

    Tech Tips

    The engine speed may be indicated as zero despite the engine running normally. This is caused by a lack of NE signals from the crankshaft position sensor. Alternatively, the engine speed may be indicated as lower than the actual engine speed if the crankshaft position sensor output voltage is insufficient.


    1. Connect the GTS to the DLC3.

    2. Turn the ignition switch to ON.

    3. Turn the GTS on.

    4. Start the engine.

    5. Enter the following menus: Powertrain / Engine / Data List / Engine Speed

      		 600 to 700 rpm: Idling (shift lever in neutral, engine warmed up and A/C off) When the crankshaft position sensor is malfunctioning, "Engine Speed" is approximately 0 rpm or varies greatly from the actual engine speed.
