P0710 — Transmission Range Sensor Circuit Intermittent
Drivable short-term, but fix now to avoid damage.
What P0710 means
This code means the signal from the transmission range sensor (also called the neutral safety switch or gear position sensor) is dropping out intermittently. The computer relies on this sensor to know your selected gear, and a flickering signal can cause shifting problems or no-start conditions. It's usually caused by a faulty sensor, corroded connectors, or damaged wiring, and is often fixable by repairing the connection or replacing the sensor.
Common symptoms
- Check engine light is on
- Transmission shifts erratically or harshly
- Engine won't start in Park or Neutral
- Gear indicator shows the wrong gear
- Transmission gets stuck in one gear or limp mode
Common causes
- Faulty transmission range sensor
- Corroded or loose electrical connector at the sensor
- Damaged, chafed, or shorted wiring in the circuit
- Misadjusted shift linkage or range sensor
- Internal transmission control module fault
Typical repair cost
$150 – $450
Varies by vehicle and root cause.
Frequently asked questions
Can I keep driving with a P0710 code?
For short trips, usually yes, but you shouldn't rely on it. Because the signal is intermittent, the transmission may shift unpredictably or even fail to start in Park or Neutral, which can leave you stranded. Get it checked soon rather than letting it linger.
How much does it cost to fix a P0710 code?
Most repairs run between $150 and $450. A simple connector or wiring repair is on the low end, while replacing the transmission range sensor and recalibrating it costs more. Diagnosis is key since an intermittent fault can take time to pinpoint.
Is a P0710 code serious?
It can be. The range sensor affects whether the car starts and how it shifts, so an unreliable signal is a real safety and convenience concern. It's not usually an immediate engine danger, but it should be addressed promptly.
Why won't my car start with a P0710 code?
Your car uses the range sensor to confirm you're in Park or Neutral before allowing the starter to engage. If the signal drops out, the computer may not see a safe gear and will block starting as a safety measure until the sensor reads correctly again.
