P1145 · NissanIntake Valve Timing Control Position Sensor Bank 2

Q: What does code P1145 mean?

Intake Valve Timing Control Position Sensor Bank 2. P1145 on Nissan vehicles indicates that the engine control module has detected an implausible or missing signal from the intake valve timing control position sensor on bank 2. This sensor reports the actual position of the bank 2 intake camshaft so the computer can verify that variable valve timing commands are being carried out correctly.

Symptoms you may notice

Illumination of the check engine light, often with no other noticeable symptoms
Rough idle or unstable engine operation, especially when cold
Reduced engine power and sluggish acceleration at low RPM
Poor fuel economy due to incorrect camshaft timing
Occasional engine stumble or hesitation during light throttle
In some cases, the engine may enter limp mode and limit RPM

Common causes, most likely first

Faulty intake valve timing control position sensor on bank 2
Damaged or corroded electrical connector or wiring to the sensor
Oil sludge or debris obstructing the sensor tip or camshaft phaser
Failed intake valve timing control solenoid valve on bank 2
Stretched timing chain or worn chain guides causing timing deviation
Engine control module software issue or internal fault (rare)

How to diagnose and fix it

Connect a scan tool and record freeze-frame data and any related codes before clearing anything
Visually inspect the sensor connector, pins, and wiring harness for damage or oil intrusion
Measure sensor resistance and compare to factory specification, then check reference voltage and ground at the connector
Remove the sensor and inspect for metal shavings or sludge; clean or replace if contaminated
Command the intake valve timing solenoid with the scan tool and verify camshaft position changes on live data
Check oil condition and level, then perform an oil and filter change if sludge is suspected
If the signal remains erratic, perform a scope test on the sensor output and inspect timing chain alignment

What Nissan Techs Check Before Replacing Parts

A dirty or sludged oil control valve often mimics a failed position sensor, so always verify oil condition and solenoid operation before condemning the sensor.
The bank 2 sensor is frequently misdiagnosed because its connector sits close to the exhaust manifold and can suffer heat damage that looks like an internal sensor failure.
After replacing the sensor, a crankshaft position sensor relearn or idle air volume relearn may be required on some Nissan models to prevent a repeat code.
A stretched timing chain can set P1145 without any sensor fault, so check live camshaft deviation data if the sensor and wiring test good.
This code can appear intermittently after an oil change if the wrong viscosity oil was used, causing slow phaser response that the ECM interprets as a sensor signal error.

Can I keep driving with P1145?

You can usually drive the vehicle short distances to a repair shop, but avoid heavy acceleration, towing, or sustained high-speed driving until the fault is repaired. If the engine runs rough or enters limp mode, stop driving and arrange a tow to prevent further damage.
