What is the air fuel sensor?
The air-fuel ratio sensor monitors the oxygen content in the exhaust stream and sends data to the computer so that it can add or subtract fuel. If there is any problem with the sensor, it can send a bad or false signal to the computer which can throw off its calculations and cause it to waste fuel excessively.
What was the error code on my Honda Accord?
I used to have both P1166 and P1167 error codes on my 2001 Honda Accord (F23A4 engine). I fixed the P1166 by replacing the O2 sensor. For about a day, everything looked wonderful (i.e. no check engine light on). Then, (after a day), the dreaded check engine light turned on again.
What does p1166 stand for on a heater fuse?
P1166 indicates a blown or malfunctioning heater core fuse. I know that O2 sensors have resistive elements inside that are activated when the engine is cold. O2 sensors operate more efficiently when they are hot. The heater element is on until the engine is at normal operating temp then it switched off.
What does the book say about p1166 and P1167?
The book says that both P1166 and p1167 is defined as the primary air/fuel sensor heater malfunction (not secondary). – shuva Nov 3 ’17 at 6:46 The Air/Fuel Ratio (A/F) sensor 1 is installed in the exhaust system and detects oxygen content in the exhaust gas. The A/F sensor transmits output voltage to the Engine Control Module (ECM).
What does P1167 stand for in EVAP code?
The heater element is on until the engine is at normal operating temp then it switched off. P1167 is the upstream O2 sensor just before the cat. If it is anything like a evap code where the computer has to relearn the sensors parameters under varying load conditions by doing tests etc.
Where is the VTEC on a Honda Accord?
The VTEC solenoid is located at the back of the engine on the left side. In the picture below, it is about 8 inches behind the orange oil dipstick. Here is the view from behind. You can see the VTEC near the center of this image with a bunch of wires going to it.
How much does it cost to repair a Honda p1166 code?
The cost of diagnosing the P1166 HONDA 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.
