Transmission Fluid Level Sensor Circuit Intermittent/Erratic
The P070E code indicates that the Powertrain Control Module (PCM) has detected an intermittent or erratic signal from the transmission fluid level sensor circuit. This sensor monitors the fluid level inside the transmission and sends a voltage signal to the PCM. An intermittent or erratic signal can be caused by a faulty sensor, damaged wiring, poor electrical connections, or low transmission fluid. This condition may lead to incorrect fluid level readings, potentially causing transmission shifting issues or damage if not addressed.
1. Symptoms You Will Notice
- Check Engine Light illuminated
- Transmission shifting harsh or erratic
- Transmission slipping or delayed engagement
- Incorrect transmission fluid level reading on scan tool
2. Most Common Causes
- Incorrect transmission fluid level (too low or too high)
- Contaminated or aerated transmission fluid
- Faulty or damaged transmission fluid level sensor
- Short to ground or voltage in the sensor wiring
- Loose, corroded, or intermittent electrical connections
- Internal failure in the TCM or PCM (uncommon)
3. Step-by-Step Diagnosis
Step 1: Use a scan tool to retrieve all stored codes and freeze frame data.
Step 2: Inspect the transmission fluid level and condition; correct if necessary.
Step 3: Visually check the sensor wiring and connector for damage, corrosion, or loose connections.
Step 4: Test the sensor circuit with a multimeter for continuity, shorts, and proper voltage reference.
Step 5: If circuit tests pass, replace the transmission fluid level sensor.
4. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended to drive with this code as it can lead to transmission damage due to incorrect fluid level readings. Have the vehicle inspected promptly.
How much does it cost to fix?▼
The cost typically ranges from $50 to $150 for diagnosis and sensor replacement, depending on labor rates and parts.
