How much does it cost to fix a p1129 code?
The cost of diagnosing the P1129 code is 1.0 hour of labor. The auto repair labor rates vary widely across the country, and even within the same city. Most auto repairs shops charge between $75 and $150 per hour.
What does the p1129 code on the intake manifold mean?
P1129 Meaning. The Manifold Αbsolute Pressure (MΑP) sensor generates a signal that is proportional to the amount of vacuum in the intake manifold. The signal is sent to the Engine Control Mudule (ECM) and the information is used to control the air/fuel mixture ratio. Faulty MΑP sensor can cuase the engine to stall, surge or a rough idle.
Can a bad O2 sensor cause a check engine light?
In most cases, a bad (O2) sensor will trigger a check engine light. P0138 and P0135 are some of the codes you may expect to see on a OBD II reader. Other than that, it’s difficult to spot a failing (O2) sensor.
What happens if you set code on downstream O2 sensor?
With this code set you will be running in open loop regardless of the reason the code is set. Constant open loop operation can’t be good for the cat. If this code only applies to the downstream O2 sensor then it will not affect the open/closed loop operation of the engine. The downstream O2 sensor controls the heat of the catalytic converter.
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 connect a jumper to an O2 sensor?
Connect a jumper between the O2 sensor 1/1 (for P1128 code) and O2 sensor 2/1 (for P1129 code) signal circuit and the O2 sensor return circuit at the O2 sensor 1/1 (for P1128 code) and O2 sensor 2/1 (for P1129 code) harness connector. The voltage should drop from between 4.1 and 5.0 volts with the jumper in place.
What does O2 sensor 2 mean on a car?
Sensor 2” does not even describe what is wrong with the heater circuit. It simply says that there is a problem with the heater circuit; that’s all. It doesn’t say that there is a failure inside the O2 sensor. If this code is the only thing the dealer has, then, it’s a wild jump to the conclusion that the O2 sensor has failed.
