Top 5 Issues with the 7th Gen Nissan Sentra (2013-2019)

1. Mass Air Flow (MAF) Sensor Codes

Signs the 13-19 Nissan Sentra Has MAF Sensor Codes

  • Check engine light, known as the “Service engine soon” light, is on for a mass air flow sensor code like P0101, P0102, or P0103

Causes of MAF Sensor Codes

A check engine light does not always mean there is a problem with the MAF sensor—There could be a problem with the electrical connector or wiring. A dirty throttle body or clogged PCV system can also throw a check engine light.

How to Fix MAF Sensor Codes

Inspect the MAF Sensor
  • Find the MAF sensor located on the air intake hose near the firewall
  • Wiggle the electrical connector and check for looseness
  • Inspect the electrical connector terminals for damage, corrosion, or discoloring like green
  • Inspect the wiring for wear like tearing or splitting
  • If the electrical connector looks okay, it might be the sensor
Replace the MAF Sensor
  • To replace the MAF sensor, remove the two screws with a 7mm socket or Phillips screwdriver
  • Remove the sensor and inspect it for debris
  • If you’d rather not replace the MAF sensor, you can try cleaning it with MAF cleaner
Preventative Maintenance
  • To prevent debris from entering the MAF sensor, change the engine air filter regularly
  • Cleaning the throttle body can also prevent MAF sensor codes

2. CVT Transmission Problems

A Nissan Sentra with CVT transmission problems is common.

Symptoms of CVT Transmission Problems

  • Engine stalls when driving
  • Car doesn’t move when shifting to drive or reverse and noise emits from the transmission
  • “Service engine soon” light is on for a transmission speed sensor code

3. Bad Front Struts

Symptoms of Bad Front Struts

  • Banging sound from the front strut area
  • Fluid leaking from the strut
  • Front end excessively bounces up and down
  • Squeaking sound from upper front strut mount when turning

Causes of Bad Front Struts

Struts wear out over time from use, and sometimes components like the bushings can wear out, leading to the symptoms above

How to Fix a Bad Front Strut

If the car needs new struts, the install steps involve removing the wheel, removing the sway bar link from the strut, and removing the bolts from the bottom and top of the strut. Reverse this procedure to reinstall.

4. ABS/Wheel Speed Sensor Codes

A Nissan Sentra with wheel speed sensor codes for the right rear wheel is common.

Signs the 13-19 Nissan Sentra has a Wheel Speed Sensor Code

  • Check engine light is on for an ABS or wheel speed sensor code like C1101, C1102, C1103, C1104

Causes of a Wheel Speed Sensor Code

A bad ABS wheel speed sensor is usually the cause for a wheel speed sensor code

How to Fix a Wheel Speed Sensor Code

Inspect the ABS Wheel Speed Sensor
  • Inspect the ABS sensor wiring for cuts or damage
  • Remove the 10mm bolt from the sensor
  • Remove the sensor
  • Disconnect the ABS sensor’s electrical connector, located on the frame next to the gas tank.
  • Inspect the electrical connector for cuts, damage, or discoloring or corrosion on the terminals
  • If the connector is fine it might be the wheel speed sensor
Test the ABS Wheel Speed Sensor with a Scan Tool

An advanced scan tool can measure the sensor’s condition and ratings when turning the wheel. If the tool gets a reading from other sensors but not the suspected sensor, it will need to be replaced

How to Test an ABS Wheel Speed Sensor without a Scan Tool

If you do not have access to an advanced scan tool, although a bit more work you can switch the ABS sensor with another on the car and see if it triggers a code

5. Ignition Coil Problems
