What does the p0141 code on an oxygen sensor mean?
P0141 Tech Notes. The code means that there is a problem with the heater element circuit of the heated oxygen sensor. The control module monitors how long it take the sensor to warm up and start sending an adequate signal. The code is triggered when the sensor is taking too long to warm up.
What does it mean when your engine code is po420?
This warning comes in an engine trouble code – PO420 or PO421. Depending on the symptoms, there are a few likely causes and solutions. For many drivers, the first sign that the catalyst efficiency is below the threshold is that the Check Engine Light turns on. In many cases, drivability will appear quite normal.
What does the p code mean on a check engine light?
Step 2: Determine the meaning of the letter. There are four possible letters that can be displayed in the first section. The letter “P” indicates powertrain-related codes such as those involving the engine or the transmission and their sensors. Typically, “P” codes are the only ones that will illuminate the Check Engine Light.
How much does it cost to repair a car p0141?
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. When is the P0141 code detected? Current amperage in the rear heated oxygen sensor heater circuit is out of the normal range.

What does the p0421 code on the Check Engine light mean?
What the P0421 code means. The powertrain control module uses data received from the upstream and downstream oxygen sensors and compares the two readings given. If the two readings are identical, or very close to each other in value, the Check Engine Light will be illuminated and a P0421 code will be stored.
What does the p1421 code on a Nissan mean?
The P1421 code is detected when The Engine Control Module (ECM) does not control ignition timing and engine idle speed properly when engine is started with pre-warming up condition. The Engine Control Module ( ECM) controls ignition timing and engine idle speed when the engine is started with pre-warming up condition.
