DPF Delete Module – Nissan Navara NP300

(15/1) PLEASE NOTE: We are waiting on the restock of these.
All orders after 15/1 will leave the week starting 22/1.

IMPORTANT:
This module is sold to be fitted to unregistered vehicles for off-road use on private property only. Removal of the DPF is an offence on registered vehicles and will make your vehicle unroadworthy.

DPF Delete module for 2015+ Nissan Navara NP300 with YS23 diesel engine. Used to simulate a valid differential pressure signal after the DPF has been removed, preventing DTC P1453 and limp mode. The ECU thinks the DPF is still fitted and everything is normal.

• No tune or ECU remap required
• The DPF can be refitted and everything returned to standard at any time

It comes in a waterproof enclosure, and is mounted in the engine bay near the brake booster. Wires connect to the MAF sensor and differential pressure sensor. Everything is plug and play – no modification to the vehicles wiring or soldering is required. The MAF sensor signal is not modified, it is only used as an input to the module to generate a valid DPS reading. Mounting bracket and bolts are included.

• No engine light
• No limp mode
• No DPF regens

A DPF delete pipe or gutted DPF must be used with this module. Do not fit this module with the DPF still in place or it will block up.
Any DPF delete pipe will work (including a bashed out DPF).
The EGT sensor must be retained in the delete pipe.
The 2 rubber hoses, steel pipes, and differential pressure sensor are not required.

Troubleshooting

If a code is present please check the following;
If the code is for the differential pressure sensor.
1. Check that all plugs are in and or/not plugged in properly or backwards. 
2. Double check the connector from the module is properly connected to the factory connector on the wiring loom (that was originally connected to the differential pressure sensor). 

Since its down under the brake booster it is a pain to access. And can be hard to tell if it's plugged in properly or not. 

4. If the origional factory connector has became brittle I've also seen the springy tab you squeeze to unplug it break off. Once that tabs gone it becomes possible to plug the connector in backwards (since the tab also prevents it being plugged in the wrong way around). 

If the code is P1453:
1. This will be module related. If he’s sure it is plugged in and plugged in correctly, get him to check none of the terminals have backed out of the connector as well. The pink module wire should also match up to the green factory wire to confirm it is plugged in the correct way.

If the code is P1546:
1. EGT sensor which is situated half way along the DPF assembly he would of removed. The plug is over the opposite side of the chassis rail and he may of forgotten to plug it back in. He should of also removed it from the DPF and fitted it to the delete pipe, and they are often very rusted in and get broken on removal. They are easily checked with a multimeter to tell if the sensor has became open circuit or not.
