Start by checking the “Possible Causes” listed above. Visually inspect the wiring harness and associated connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector pins.

| P1288 code technical notes

This indicates that the cylinder head temperature sensor (CHT) is outside the self-test range. The engine is not at normal operating temperature.

| What are the possible symptoms of P1288 code?

  • Check engine light on (or service engine soon warning light)

| What does P1288 code mean?

The cylinder head temperature sensor (CHT) is mounted in the cylinder head wall and is not connected to any coolant passages. The CHT sends a signal to the powertrain control module (PCM) indicating the cylinder head temperature. If the temperature exceeds 126°C (258°F), the PCM shuts off four fuel injectors at a time. The PCM will alternate the four disabled injectors every 32 engine cycles. The four cylinders that are not injected with fuel act as air pumps to help cool the engine. If the temperature exceeds 154°C (310°F), the PCM shuts off all fuel injectors until the engine temperature drops below 154°C (310°F).

  • Engine Light On (or Service Engine Soon Warning Light)
  • Possible rough engine idle

| What does P1288 2004 NISSAN MAXIMA code mean?

The A/F sensor is a planar dual-cell limit current sensor. The sensor element of the A/F sensor is the combination of a Nernst concentration cell (sensor cell) with an oxygen pump cell, which transports ions. It has a heating element inside the element.

The sensor is capable of accurately measuring λ=1, but also in the lean and rich ranges. With its control electronics, the sensor emits a clear and continuous signal over a wide range (0.7 < λ < air).
The exhaust gas components diffuse through the diffusion gap at the oxygen pump electrode and the Nernst concentration cell, where they are brought to thermodynamic equilibrium.
An electronic circuit controls the pump current through the oxygen pump cell so that the composition of the exhaust gas in the diffusion gap remains constant at λ = 1. Therefore, the A/F sensor is able to indicate the air/fuel ratio by this pumping current. Additionally, a heating element is built into the sensor to ensure the required operating temperature of 700 to 800 C (1,292 to 1,472 F).
