How to Fix Code P1135 SCION?

Start by checking the “possible causes” listed above. Visually inspect the corresponding wiring harness and connectors. Look for damaged components and check for broken, bent, pushed out, or corroded connector pins.

When is the code detected?

P1135 is set when the Engine Control Module (ECM) detects a malfunction in the heated oxygen sensor heater circuit

Possible Symptoms

  • Check Engine Light On (or Service Engine Soon Warning Light)

P1135 SCION Meaning

The Air Fuel Ratio (A/F) Sensor must reach a minimum operating temperature of 1200 degrees F to produce an accurate voltage signal. The faster the Air Fuel Ratio Sensor reaches this temperature, the sooner the sensor will start sending an accurate signal to the Engine Control Module (ECM).
To reach the required temperature, a heating element is included inside the Air Fuel Ratio Sensor. The ECM controls the Air Fuel Ratio Sensor heating element based on signals from engine coolant temperature and engine load. The ECM controls the heater circuit by allowing current to flow to ground.
The ECM monitors the voltage signal received through the heater circuit and determines the circuit’s status by comparing the detected voltage to factory specifications.

P1136 – Intake Valve Control Solenoid Circuit, Bank 2

P1136 Possible Causes

What does this mean?

  • Faulty intake valve timing control solenoid, bank 2
  • Intake valve timing control solenoid 2 circuit open or shorted
  • Poor electrical connection in intake valve timing control solenoid circuit, bank 2

How is code P1136 repaired?

Start by checking the “possible causes” listed above. Visually inspect the corresponding cable harness and connectors. Look for damaged components and check for broken, bent, pushed out, or corroded connector pins.

Technical Notes

Since the intake valve timing control solenoid uses oil flow to control timing, dirty oil can cause the valve to stick open or closed. Before replacing the valve, change the engine oil and filter and reset the engine code. If the code returns, you can remove the intake valve timing control solenoid and clean it with brake cleaner.

Possible Symptoms

  • Check engine light on (or service engine soon warning light)
  • Possible engine power loss/lack of power
  • Possible rough engine idle

P1136 Meaning

The intake valve timing control solenoid is activated by pulse (duty ratio) on/off signals from the engine control module (ECM). The intake valve timing control solenoid changes the amount of oil and direction of flow through the intake valve timing control unit or stops the oil flow.
Longer pulse width advances the valve angle. Shorter pulse width retards the valve angle.
When ON and OFF pulse widths become equal, the solenoid stops the oil pressure flow to lock the intake valve angle at the control position.
Diagnostic trouble code (DTC) is set when incorrect voltage is sent to the ECM via the intake valve timing control solenoid.

P1136 AUDI Meaning

This trouble code is stored in the engine control module (ECM) when the ECM is no longer able to control the air-fuel ratio. For proper catalytic converter operation, the ECM must maintain the air-fuel ratio (AFR) at approximately lambda 1; this equals an AFR of 14.7:1 by mass. This is achieved by adjusting the fuel mixture to the required amount to account for slight anomalies under normal operating conditions. However, when a fault causes the fuel compensation to exceed a predetermined level, the malfunction indicator light is turned on and a limited operating strategy is employed. The pre-catalyst exhaust gas oxygen sensor is the main component used to calculate fuel compensation once the system enters closed-loop control. Fuel compensation data can be displayed as a percentage, positive or negative.
This diagnostic trouble code (DTC) can be caused by a faulty mass air flow sensor, fuel pressure regulator, fuel pump, exhaust or intake leaks, secondary air injection leaks, or vacuum leaks. Additionally, any mechanical fault can also cause this DTC. Common failure points associated with this code are a damaged EVAP purge control valve, brake booster and hoses, electric vacuum pump (if applicable), PCV, or a ventilation system.
