Without further delay, let’s get started by describing the process of pulling a Honda car make without a scanner.

How to Pull Honda Codes Without a Scanner: The Ultimate Methods 

Pulling the Honda codes via manual means is a super simple and fast process.

A necessary tool you ought to have is a metal wire. Essentially, this thin metal wire should have a metal clipper.

Also, a booby pin can be used along with the wire and this tool should lack the pointing part.

As we said earlier, pulling Honda codes without using a scanner is not a complex process.

Follow these three methods and you will be able to detect codes and repair this monster car effectively.

Never should it be cumbersome to detect flaws affecting the Honda car make if you have this info by your finger point.

Honda Trouble Codes List: Top 10 Codes 

Like other automotive makes, Honda cars can flaw and it’s vital to troubleshoot them to locate the real problem.

In this section of how to pull the Honda codes without a scanner review, we are going to detail and elaborate on some common trouble codes.

01. 02A Trouble Code

An error code that shows malfunctioning of the rear oxygen sensor. In case there is low or high voltage, the O2 sensor fails to read the right amount of oxygen found in the exhaust.

As a result, this leads to a malfunction or complete failure.

02. 02B Trouble Code

An error code that varies in terms of the voltage supplied to the oxygen amount in the car exhaust. Varies from 0.1 – 0.9 voltage.

For 0.1 V, there is low exhaust, while 0.9 V indicates excess exhaust.

All in all, this trouble code affecting the O2 sensor component depicts low or extreme or has become inactive.

03. MAP Trouble Code

Depicts a problem affecting the MAP sensor with extreme voltage input directed to the ECU.

Extreme voltage is a commonly experienced flaw that prevents proper engine operation in terms of operating the MAF and TPS.

04. CKP Trouble Code

An error code is harnessed when the PCM cannot detect the right sensor functioning around the crankshaft sensor.

A car with this type of code will display CEL on the dashboard area, making a failsafe mode to be enabled.

05. P0107 MAP Trouble Code

A Honda trouble code that shows the sensors have low voltage input to the ECU. Encountering this code means that the overall input voltage is around 0.5 or much lesser.
