Code C1130 Description

The C1130 engine signal 1 code refers to a communication error between the engine control module (ECM) and the electronic throttle control (ETC) system. This code is commonly found in vehicles with electronic throttle control systems, which regulate the amount of air entering the engine for combustion. When this communication error occurs, it can lead to various performance issues in the vehicle. The engine may run rough, have reduced power, or even stall while driving. Additionally, the vehicle may experience poor acceleration, decreased fuel efficiency, and potential drivability issues. If left unresolved, this code can lead to further damage to the engine and other related systems, potentially resulting in expensive repairs down the line.

  • Hello, I have a 2013 Nissan Altima S 2.5L. We had the code P2097 for the O2 sensor, we had it changed when the car started to have multiple issues. It was bad on gas, it would jerk in the middle of driving, when we would start it, it would die right away, we would press the gas pedal but the car wouldnt go or would barely go which I read was "limp mode". We changed the O2 sensor and the car was acting worse. We took it and put it on a code reader and we received the following codes. C1130, C119A, B142A, B00A0, P0965, P0841, P0848, P2097, P0776, & P1715. I just dont know where to start and need help on what to start to fix first.

  • There are no common components between all the codes you got. Some are for the airbag system, ABS, and even the transmission. I recommend starting by clearing all the codes, then check what code comes back first. Also check the transmission fluid level and condition, All these codes are for the transmission and could be set by low transmission fluid (P0965, P0841, P0848, P0776, & P1715).

  • Thank you for answering my question. I did find out that the airbag and the ABS codes are from a recall they have for my car. Those 2 are going in for that once I can get the rest fixed. These may sound like a girl thing lol but, how do I reset the codes?

  • You can either use an OBDII scanner or disconnect the car battery for about 30 minutes.

  • Start by checking the transmission fluid level and condition. When was the last time you change the transmission fluid?

  • I am not sure maybe a year ago. I take it to sears and they just take care of what's needed as needed.

  • I recommend starting with the transmission service. Servicing the transmission fluid may fix the problem and is part of the maintenance of your vehicle.
