diagnostic check engine light

P0825 code definition

The P0825 code is a generic powertrain code related to the transmission including pressure faults and sensor failures. In this case, the engine control module (ECM) has found a fault in the electrical circuit of the gear lever push-pull switch to transmission range correlation circuit.

Codes related to the P0825 include:

  • P0820: Gear Lever X-Y Position Sensor Circuit
  • P0821: Gear Lever X Position Circuit
  • P0822: Gear Lever Y Position Circuit
  • P0823: Gear Lever X Position Circuit Intermittent
  • P0824: Gear Lever Y Position Circuit Intermittent

What the P0825 code means

An gear lever push-pull switch is used on vehicles with a manually shiftable automatic transmission. If the ECM is sent a voltage or resistance signal through the Gear Lever Push-Pull Circuit that is outside of allowed variances, a P0825 code will be stored.

What causes the P0825 code?

Several problems may cause a P0825 code including:

  • Liquids spilled onto the gear lever push-pull switch inside the passenger compartment
  • Faulty, damaged, or defective gear lever push-pull switch
  • Faulty or defective gear lever push-pull switch
  • Damaged, corroded, or disconnected electrical wiring and connectors to the gear lever push-pull switch

What are the Symptoms of the P0825 Code?

Symptoms of a P0825 code may include:

  • A check engine soon or warning light may illuminate
  • The manual shift option may be disabled
  • The vehicle may have no symptoms other than a stored fault code
  • Overdrive light may flash
  • Decreased fuel efficiency
  • Vehicle may shift roughly
  • Transmission may go into “limp” mode

How does a mechanic diagnose the P0825 code?

A mechanic may use several methods to diagnose a P0825 trouble code, including:

  • Utilize an OBD-II scanner to check for a stored P0825 trouble code
  • Visually inspect the passenger compartment for any spills that may have got into the up and down shift switch
  • Visually inspect the circuits wiring for signs of damage, corrosion, or wear
  • Check reference voltage and ground signals at the gear lever push-pull switch and actuators
  • Use digital volt/ohmmeter to check for continuity and resistance if reference voltage and/or ground signals were open
  • Test all related circuits and switches for continuity and resistance

Common mistakes when diagnosing the P0825 code

Before checking and diagnosing faulty transmission wiring, be sure to check whether liquid was spilled on the shifter in the passenger compartment. Clean and repair any damaged wiring or connectors at the shift switch location, then reset and retest the system before diagnosing and performing more complicated wiring repairs.

How serious is the P0825 code?

Because a vehicle’s safe driving operation may be impacted due to faults that store a P0825 code, this code is considered a potentially serious code. When this code appears, it is recommended to immediately take your vehicle to your local service center or mechanic for repair and diagnosis.

What repairs can fix the P0825 code?

Several repairs can fix a P0825 trouble code and include:
