Do you want to know all the necessary and important information about the P1122 Code? If yes then you are reading the best article on the internet because I will explain all the necessary information about P1122 Code.
All drivers need to know as much information as they can about their car because it will help them to use the car properly, maintain and discover minor and major problems quickly which will save them from repairing accidents, and damages.
What Does the P1122 Code Mean?
It is very important to know the meaning of the P1122 code, this will allow you to have more understanding of the code.
P1122 code means Electronic Throttle Control Actuator, which consists of a throttle control motor, Throttle Position Sensor (TPS), etc.
The throttle control motor is operated by the Engine Control Module (ECM) and it opens and closes the throttle valve.
The throttle position sensor helps to detect the throttle valve position, and the opening and closing speed of the throttle valve and feeds the voltage signals to the ECM.
The ECM judges the current opening angle of the throttle valve from signals and the ECM controls the throttle control motor so that it will be able to make the throttle valve opening angle properly in response to driving conditions.
What is the Cost to Diagnose the Code P1122?
When your car shows the P1122 code, then you should know that there is a problem that needs to be fixed immediately to avoid severe or additional problems.
All drivers need to know the cost to diagnose the P1122 code. This will help you to prepare when going to your mechanic and also help you to get it done at the right price so that you won’t be scammed.
Currently, the cost to diagnose the P1122 code is just 1.0 hours of labor. Although it depends on the car make, model, engine type, auto repair’s diagnosis time, and labor rates in your location or country.
Most auto repair shops charge from $75 to $150 per hour.
How to Fix the P1122 Code?
Before you begin to fix the P1122 code, you need to begin the process by checking the “Possible Causes” listed in this article. You need to visually inspect the wiring harness and connectors. Check for damaged components, check for broken, bent, or pushed out,
What are the symptoms of code P1122?
There are several symptoms of code P1122 on Nissan and other car makers but could include one or more of the following.
- Idling speed may fluctuate, or the idling may be rough- usually because the idling speed is too low
- Idling speed may exceed the specified or recommended speed
- Gear shifts may be harsh, erratic, or unpredictable
- Severe loss of power loss may be present
- If a fail-safe or limp mode is initiated and enforced, neither the throttle nor the transmission may respond to manual inputs.
- The engine may stall unexpectedly- especially at low engine speeds or when coming to a stop
- Stored trouble code, and illuminated warning light
- In many cases, multiple additional codes may be present along with P1122, and most notably, codes that relate to mis-correlations between the throttle pedal position sensor and the throttle position sensor
- The engine may be difficult to start, or the engine may not start at all
- The engine may not respond to throttle inputs as expected, or may not respond to throttle inputs at all
What are the Possible Causes of the Code P1122?
These are the major causes of the P1122 code.
- Failed PCM, but you need to know that since is a rare event, the fault can be sought elsewhere before any control module is replaced
- Damaged throttle pedal position sensor
- Defective or worn throttle body
- Damaged, burnt, shorted, or corroded wiring or connectors anywhere in the throttle body’s control signal circuits
- The defective, damaged, or worn throttle position sensor
- Defective or worn drive gears in the throttle body
- Defective or damaged stepper motor in the throttle body.
- Electric Throttle Control Actuator circuit bad electrical connection
- Excessive carbon build-up may stop the free movement of the throttle plate
- Use of aftermarket throttle bodies
- Failure to perform required adaptations or relearning procedures after a throttle body replacement
