When do I get an error code p1126?
Error Code P1126 is determined when there is an excessively low voltage power from the throttle control motor detected by the PCM. Or the engine coolant temperature doesn’t reach the temperature specified by the manufacturer even though the engine has run long enough.
When to run the p1128, p1129 code?
P1128, P1129 code – This diagnostic runs when the following condition are met, shortly after engine start up, fuel level above 12%, battery voltage above 11. volts, no active bank 1 fuel injector, ignition coil, or upstream O2 sensor circuit faults.
How to test p1128 Bank 1 and 2?
Turn the ignition on with the scan tool actuate the sensor 1/1 heater test (for P1128 code) and 2/1 heater test (for P1129 code). With the scan tool monitor O2 sensor 1/1 (for P1128 code) and 2/1 (for P1129 code) voltage for at least two minutes. Does the voltage stay above 4.5 volts?
What does p1128 mean on a Dodge Charger?
Start by checking the battery charge and terminals, and alternator charging. If the battery and alternator are OK, the Totally Integrated Power Module may be damage. What does this mean? The cost of diagnosing the P1128 DODGE code is 1.0 hour of labor. The auto repair labor rates vary widely across the country, and even within the same city.
What causes a p1128 trouble code on a Dodge?
Getting a P1128 trouble code on a Chrysler or Dodge product may lead you to believe you’ve go a bad thermostat or engine coolant temperature sensor because P1128 is: P1128 Closed loop fueling not achieved Bank 1 The symptoms appear as hesitation, stalling, misfire.
What does Bank 1 on a p1128 mean?
A P1128 Closed Loop Fueling Not Achieved – Bank 1 means that the PCM isn’t seeing the O2 readings it needs to change from open loop (default factory programming determines air/fuel mixture) to closed loop (PCM varies air/fuel mixture based on live readings from all sensors).
How much does it cost to diagnose Nissan code p1126?
The cost of diagnosing the P1126 NISSAN code is 1.0 hour of labor. The auto repair labor rates vary by location, your vehicle’s make and model, and even your engine type. Most auto repairs shops charge between $75 and $150 per hour. When is the P1126 NISSAN code detected?
How to check O2 sensor for p1128 code?
No, check the O2 sensor 1/1 (for P1128 code) and O2 sensor 2/1 (for P1129 code) signal circuit for a short to ground, open or short to voltage and repair if necessary. Inspect the O2 sensor 1/1 (for P1128 code) and O2 sensor 2/1 (for P1129 code) connector and the PCM harness connector.
What is the error code for throttle control?
Table of Contents. Error Code P1126 is defined as Throttle Control Motor Relay Circuit Open. This means the voltage power source for throttle control is excessively low, which could be a case of leak in the seal or the thermostat is stuck open.
How does the throttle control motor relay work?
The latter is turned On/Off by the former; when the ignition is switched off, the PCM will send a signal to the throttle control motor relay and a battery voltage is provided to the PCM. When the ignition is switched off, the PCM will send an off signal to the throttle control motor relay and battery voltage will NOT be provided by the PCM.
Where does the power supply for the throttle control go?
The power supply for the throttle control provides the PCM (powertrain control module, also known as ECM or engine control module) through throttle control motor relay.

When does the service engine soon light come on?
If your Check engine light is ON, the easiest way to diagnose this problem is to always check your trouble code memory with an OBD2 scanner. The check engine light will not light up if there is a scheduled service as the service engine soon light. It does only occur when there is a problem with your engine.
What to do if your engine maintenance light goes out?
Check your engine control unit for any stored trouble codes. If you receive any codes, save them and try to get information about what they mean. If there are codes for emission problems that are not dangerous for your engine, you can try deleting the code to see if the engine maintenance light goes out.
Why does my check engine light not light up?
If your Check engine light is ON, the easiest way to diagnose this problem is to always check your trouble code memory with an OBD2 scanner. The check engine light will not light up if there is a scheduled service as the service engine soon light.
What does the trouble code p1126 mean on a car?
This means the voltage power source for throttle control is excessively low, which could be a case of leak in the seal or the thermostat is stuck open. This engine code is a generic trouble code, meaning it applies to all vehicles equipped with OBD-II system, or vehicles made since 1996 up to present.
